[@sparklephoenix9743]

Hello Leo, I liked your video explaining passkeys. You explained it very clearly. I have some questions concerning passkeys left, e, g, 1. Google may know that its definitely me, but how do I know that it's Google asking ? This is even worse with you saying passkeys might work in the background without me even knowing. Let's assume someone breaks into Google and steals my public key. Computers are able to ask my number thousands of times in seconds. With enough returned numbers they might be able to "assemble" my private key. 2. If a passkey is stored in my device: What happens if I change hardware or have a major operating system update or change my operating system on this device? After a major OS-update my husband was in trouble. To what part of my device is this passkey linked? Hardware or software or both? 3. I use a password management tool and they do a lot of advertising for passkeys. I think it is a good idea concerning websites, but I won't change my master password to a passkey. If someone breaks into one of my devices, he will have access to my password management. My master password is only in my head. 4. I have a friend who is a mathematician. He told me, encryption is all based on large prime numbers. Of course there are infinite prime numbers, but the larger the more diffcult to identify they are. So there might be "doubles" in the known and frequently used range of prime numbers. This is another gateway a backentrance not mathematicians never know and think about. What do you think about these questions, especially No 1? Kind Regards Sparkle_phoenix

1. For phishing and fake websites passkeys are such an improvement over passwords. For one they would need access to the public keys assuming these aren't even protected in another layer of encryption on the servers end but even with that it wouldn't work as passkeys are tied to the origin (website) so a fake website wouldn't be able to authorise this request. (I'm not sure to the extent at which this can be worked around, possibly a passkey API vulnerability for a browser allowing you to fake the origin but this may also be tied specific secrets on that end such as public site certificate, etc). Keys stored on separate platforms like apple, andoid, etc. also use bluetooth when signing in from lets say windows which is another form of protection against phishing as the device needs to be physically in range for the authentication to be successful while also behind the extra layers of security your device offers like biometrics. 2. Passkeys can either be device bound or synced. For example, device bound passkeys can't be exported such as with windows storing them in the TPM but can be lost by design, what your probably looking for is synced passkeys like with apple, passkeys are stored in icloud keychain which is synced between your devices as well as many password managers supporting synced passkeys. For most services, you can also setup multiple passkeys for other devices. 3. Some people like to store their passkeys and passwords in the same password manager together which can be good and bad but ideally if you have a master password and two factor for your password manager then you should be good especially if stored locally (which I believe all password managers that you use should be) just making sure you follow the 3-2-1 backup strategy so you don't lose access keeping encrypted backups of your databases, keys and 2fa backup codes. Furthermore, most password managers offer extensions so you can automatically sign in with the passkey (if they support it). Adding onto the security, since the authentication with your private key is done locally and never leaves your device, it can't be intercepted because it's never transmitted and no third party will have access to it. 4. Some services so far have adopted the passkey standard greatly while others are still a bit of a hassle such as google. Since passkeys are cryptographically signed and verified, these can be used to identify you so you don't even need to provide something for identification like a username or an email, you can just straight up use the passkey. Mathematically, yes a hash collision can happen where two inputs can produce the same output but statistically it's functionally "impossible" that the chances of it happening are pretty much zero.

[@jeannehallock951]

As your normal stupid users, I just went through this with my son. He factory reset his phone which wiped his passkeys making it impossible to get into his google account (which he used for all of his college communication). Until learning about this technology about 2 days ago, I had no clue this is what happened. Safe maybe, but not "fool" proof if you have no idea that a passkey is automatically being set on your phone or that you are even setting up a passkey or what a passkey is. Nor would I call it less frustrating.

[@VerticalBlank]

Yeah I would only ever use passkeys with a password vault for this exact reason. Think of them like SSH keypairs.

[@pierres_blog]

Even with passkeys, we should be noticing what the passkey reset procedure is for any given account. Usually it's by an email - which is simultaneously handy and horribly insecure.

[@BrotherMichaeloftheCross]

You make really good points, but Microsoft's system glitches now and again and they prompt you to sign in. It happens too often for me and I don't know why. It is possible for Microsoft themselves to fail and you might have to work a little to get signed in. If the time arrived when their system didn't work, I would be unable to sign in, The break down of systems you described is not very likely, but Microsoft itself is subject to frequent glitches that leave you stuck until they are satisfied you are who you say you are.

[@Ultrajamz]

If I understand, the real advantage I see, is just that passkey’s are device specific. Is that always the case by definition? Also can they really replace passwords? Doesn’t the account need it anyways for the scenario of not having the original device anymore? Can’t malware get device info to allow it to be spoofed?

[@askleonotenboom]

Passwords are not needed, as long as there's a different way to authenticate -- like an email sent to the account of record, or a message sent to a phone.

[@Ultrajamz]

@@askleonotenboom I guess I am thinking of very critical items and odd situations. In another country, phone stolen, need to get into my email… can’t if its a passkey only. With a memorized password I have a chance. (Ignoring the hail mary of “question based password reset”)

[@Ultrajamz]

To add to that, it seems from what I see… we can’t export passkeys… meaning if I built up all this history of passkeys with windows hello (or whoever)… I’m pretty dang locked in… if they change policies or I don’t want windows apps installed on my linux box, or move to macos… issues!

[@askleonotenboom]

I don't see how you're locked in at all. Basically you set up a passkey on a new device, or you can invalidate the passkey on the current device and set it up anew.

[@Ultrajamz]

@@askleonotenboom so say I have 30 passkeys for 30 websites with windows hello. I decide I don’t want windows hello anymore I want to use bitwarden instead. I now need to 1 by 1 set this up all anew for each of the 30 sites because there is no “export/import” standard for the passkey… that friction is so high it may as well be lock-in, no?

[@chrisluke2264]

Question. First, nice job explaining things. You provide a lot helpful information. Don’t you need/have a username and password to create an an account on a website? So, even if you have a passkey, couldn’t someone use your username and password to sign in? Even if you set the default sign in to be a passkey? Or, if you don’t have your phone handy and want to sign in on a friends computer to check your email. What happens in that case? I think passkeys are a great idea but before I start using them I want to know the “what if” scenarios. And what do you do when you get a new phone? Thanks.

[@askleonotenboom]

Not necessarily. Services are moving to being passwordless. When you attempt to sign in the first time they authenticate you some other way, like an email to an alternate email address, or a text message, or a notification on an app.

Great video. I like how you talk about different attack vectors to have different levels of relevance and mitigations. It's crucial for people to understand the efficacy of security features like passkey.

[@StijnHommes]

16:00 Sending an email to an account and expecting someone to hit a link to login ignores that you should never click in links in an email. (and those emails often take not just a little while but more than 24 hours, or they simply never show up) 20:00 If I can't even use my password vault on a computer that doesn't have it installed, using it to store passkeys is not going to help me sign in, since you can't even practically type them. I still need to type in my password after opening my vault and keep my password storage offline.

[@marcusaureliusf]

What I'm worried about is this: now the same PIN that unlocks my device can unlock my accounts. So if you give your PIN to a family member to play some games or in case you're driving and you want somebody else to look something up on Google Maps (or, worst case scenario, if you need to give your PIN to a robber) they'll have access to everything. I think I'd miss the option to have at least two access levels to my stuff.

[@CRan-ei6co]

Yeah that seems to be one the main concerns (especially revolving around biometric laws pertaining to breach of a persons device) however you can use third party solutions like password managers and store passkeys there behind a master password and forms of MFA, these aren't device bound and can be synced as well allowing you to share certain passkeys if needed or easily backup. These apps can also be installed on your mobile device however I prefer not to sync things in the cloud and keep everything local and backed up.

[@skeletala]

How about ubikeys as a DB for your password manager? every OS should have a PM and the passwords should be stored in a ubkey or a normal USB key. 1. password managers generate secure passwords 2. the passwords DB (ubkey/usb stick) is the 2nd factor.

[@GaryV-p3h]

I would like to see sensitive data such as banking apps & websites protected by 2 factor biometrics, face ID plus fingerprint, making sure that it can only be me accessing these accounts.

[@askleonotenboom]

That's in a sense what Passkeys provide. If you have biometrics support on your device, that's how you unlock it so a passkey can be used.

[@Ck87JF]

I think maybe they're suggesting that banks and other such places that store highly sensitive info often use SMS or email based 2FA which are far less secure than TOTP or Passkeys.

[@Mattias1995]

If I store my Passkey in a password manager, and that password manager is leaked (either through malware or hacking of the password manager vendor itself), doesn’t that mean the hacker has access to everything? Previously you would have passwords in the manager, and then say a 2FA code in another app or location, and that would require the hacker to hack both services, which is a lot less likely? Or am I missing something here?

[@silvieb2024]

Absolutely 💯%.

[@steelpanther88]

one thing that you always see in the CSI type TV shows just lift your greasy fingerprint off from a jar of glass and input that to unlock finger print ID. So, if it really is that simple to bypass fingerprint ID (and fingerprints are not private secrets - unlike secret knowledge like passwords) then whats the real benefit. So the real scenario is that if you are using fingerprint ID and passkey and you are in online cafe and windows is locked. then if someone has "stolen" your fingerprint, they can just unlock everything ?

[@askleonotenboom]

I'm not one to believe everything is as easy as they show on TV. Besides, you would have to be an EXPLICIT target for that scenario to even play out. Most of us just aren't that interesting.

[@pbrigham]

You forgot that also with passkeys, no more Phishing as the key will not work on a fake website.

[@StijnHommes]

Who cares. Hackers will find a way to use them on the real website that is the target anyway. You can spoof an IP, you can spoof your GPS location. It might take slightly more effort, but you can also spoof my identity.

[@pbrigham]

@@StijnHommes No, with a hardware key like Yubico the login is only possible with the key itself, no key, no login, is that simple.But even more important than that, is that there is nothing to hack because the only thing stored is public key that is complete useless, the private key is always in the hardware key itself in yours possession.

[@aerialdude]

@@StijnHommes You are mistaken. With a passkey, a phishing site will only get your public key (not your private key). With only the public key, there is virtually no possibility that an attacker could reverse engineer your private key (which is what they would need to do in order to sign in to the real website).

[@freescape08]

I would have to better understand how the handshake works before changing to passkeys. Is the private key only ever on your device? Does your device do the comparison with the public key? (If so, couldn't the confirmation be spoofed to the server? And if not, couldn't someone pretend to be the server and request your private key?) Could someone spoof the public key after a data breach? I'm still not hearing the details.

[@pbrigham]

@@freescape08 You can have only the key on the device, but I don't use that, I use hardware Yubikeys ( There is other brands but the principal is the same ), my keys can NOT be copy or replicated in any shape or form, no Yubikey no login as simple as that, obvious I have several so I don't get lock out in case I lose one, I have configured them with a pin also, wrong pin 3 times and that yubikey is blocked, security wise at the moment is the best method on the market, period.

Windows Hello face recognition has been cracked insofar as someone with a very specific intent to access your computer can take a picture of you, convert it into a special type of image, and use some specialized hardware to trick your computer that a new webcam has been plugged in and that you're sitting in front of the computer. But this is a very targeted attack vs one that can be launched across the world automatically, so it's less likely to occur. But yes, with this attack, whatever Passkeys that Hello is securing would be made available. You could instead secure Windows Hello with a security key like a Yubikey (and secure that with a strong PIN you've not used anywhere else).

[@TomCarrollJr]

According to Chat GPT / Gemini answers, Passkeys are designed with security in mind, and by default, there currently isn't a way for a surviving spouse/partner to access your data directly if you pass away. This is because passkeys rely on biometric authentication (like fingerprint or facial recognition) or a physical security key for verification. Any thoughts on that?

[@askleonotenboom]

Or a PIN, on Windows machines. Not sure what thought you'd want me to have? Disaster planning is important, and I have videos/articles on the topic. Passkeys don't alter that.

[@Ck87JF]

As Leo suggested, you want to plan these things with your partner. You can set up a password manager with shared access in which you store very long & complicated passwords for certain systems like email and banking. And then if you store Passkeys in them, that should get you in without needing biometrics. Windows Hello and other systems that do the back end authentication can usually take multiple fingerprints, so you could store prints from both of you. The backup Windows pin could be a long phrase like "apple zebra sander ketchup beach horse 385326$" that you store in the shared password manager so even if biometrics don't work, you can still access the computer.

[@askleonotenboom]

"Access Denied"

[@Meowski_2]

🤨 .... Better Ask Leo, to figure out why

[@ninakim7282]

GREAT.

[@bme7491]

I couldn't care less about Google or Microsoft. The real disaster is that almost every banking/financial institution website in the US doesn't offer passkey 2FA.

[@askleonotenboom]

Agreed. They should offer 2FA options beyond SMS ... and yet, here we are.

[@mikey4016]

More ways to get hacked. If you want your banking to be secure, don't use online banking and tell your bank that any attempts to set up online banking are fraudulent.

[@StijnHommes]

Passkeys can't be safe, but more importantly, they increase the risk of the account owner not being able to get in and that is a serious problem.

[@askleonotenboom]

This is incorrect. You will not lose access to your account if you lose your passkeys. See "Passkeys are never the only way in" in askleo.com/passkeys-and-disaster-planning/

[@StijnHommes]

@@askleonotenboom So the other ways in can get leaked as well. As long as there are recovery options, they will be abused, so effectively, it's no safer than using a PIN number on the account itself. And if the device carrying your passkey is ever lost, broken or stolen, you have to reauthenticate to all your accounts with the new device to get new passkeys. And that is skipping another important point, logging into Windows with a PIN is much, MUCH less secure than a well-chosen long and unique password, because a PIN has a much more limited character set that can easily be brute-forced. [and no, not every device has a camera or fingerprint scanner, and even if they do, those things can also break -- and we should have to leak biometrics to get into our accounts.]

[@StijnHommes]

@@askleonotenboom Let me be clear: if someone knows your Windows Hello PIN number and is thus able to unlock your PC, a passkey offers no additional protection because it opens with the EXACT same credentials. The passkey itself might be entirely unique, but it is sent based on the exact same code you enter. Using a password means they need to know your Windows Hello PIN AND the password to the account they want to sign into. Two [different] steps is automatically more secure than one.

[@CraigLong]

@@askleonotenboom Can we keep the hacker from using those other methods of getting in? To use a less secure method it would be nice to use some authentication.

[@Ck87JF]

​@@CraigLongsome sites allow you to disable some methods of authentication, but other sites are much less configurable.

[@monza8844]

It's not a good system when it takes 22 min to explain.

[@mikepanchaud1]

Not true. I set up my Google account with my finger print in a minute before I saw this video. I now feel secure and educated, having watched it!

[@Kenionatus]

Ideally, end users don't need to know how it works behind the scenes. It's already that way with sessions cookies and similar tokens.

xkcd comic 538 is relevant here.
