What do you think about security keys? Let us know in the comments below! If you found this video interesting, be sure to give it a LIKE and SHARE it with people who might be interested in getting a security key! Thanks for watching.

[@nananikinas8864]

I guess IF the iPhone 15 goes USB-C or Thunderbolt it would be good to keep that in mind before buying one of these.

[@James20000]

I think security keys are great, because they can help protect your passwords, and Two-Factor authentication codes.

[@ironsidefan]

These keys are a step backwards. As an example banks have been working for decades to streamline and simplify transactions to where eventually we no longer need even a physical card (e.g. credit or debit), but for the last year now if you’re a landlord with tenants in say an apartment building or a mobile home or RV park the banks charge you a hefty fee for each rent payment transaction for each tenant if you allow the tenants to use either a credit or debit card. So what has this resulted in? As a tenant you must now pay your rent bill with a written cheque - do you get my point?

[@javtimestwo]

@@ironsidefan seems like a bad idea for so many reasons. not interested at all in carrying one or two more things and then running the risk of losing such important items. NOPE!

[@plaherne79]

@MostaTheGamer013 - even if you are right about them going wireless for the iPhone 17, they have no choice but to use USB-C for the iPhone 15 & 16 because of EU regulations. They are essentially being forced to use USB-C for these phones.

Pro tip: keep your car key separate from your other keys. If your car gets jacked you don't lose your other keys. It's also better for your ignition switch not to have the weight of all your keys hanging from it.

You carry it in your pocket and never have to put in ignition. Separate ring to give only car fob to auto technician. That was always a good idea.

[@rogerf3622]

Once setup, you only need the security key if you are planning on setting up a new Apple device or going online to use iCloud. You do not need to carry this key with you or even use it for months or years. Your phone or iPad will not ask you to reauthenticate itself with this key. Also, you are NOT setting up a security key on that device. You are setting up a security key on your Apple account using that device. Once you setup a security key, all your other Apple devices know about it. The only reason to ever carry a security key is if you are also using the same key on a specific website that you have configured to use it. Some people will configure their Mac or PC to login using the same security key in which you may have to actually carry it with you. But this is a completely different issue that setting up an Apple account.

The OTP apps are better but you could still accidentally enter them into a fake login page.

[@defyiant]

@@wolfsonryanthis is why you have a backup key and backup codes saved in your password manager of choice.

[@fredoswego]

Since you need 2+ keys (aka a backup) I can see it making sense to go with a cheap one as the one that sits at home in your fire-safe or safety deposit box. When you lose/break the more expensive version you use the cheap backup so you can add the replacement. I think the design of the NFC keys needs to be rethought though to make them more suited to being something you'll have on you 24/7. I can't picture any of those plugs surviving too long on a populated key-ring in your pocket. Something is going to break/bend. Perhaps an actual NFC ring you wear. One hand wedding band, one had NFC band.

[@PayetteForward]

Hi Fredoswego, Thanks for your comment! It's true that having a backup key is essential, and having a cheaper one makes a lot of sense. We totally agree that the design of NFC keys needs to be rethought - it would be great to have something that you can keep on you at all times without worrying about any damage. An NFC ring is an interesting idea - we'll keep it in mind for future videos! Best, David P.S. You can support us by becoming a channel member: kzbin.infojoin

[@cda3715]

@@PayetteForward ​ does this mean that if someone steals your phone they cannot change your passwords to you Apple ID and hijack your entire ID when using these security keys? Also it’s so confusing. Security keys and then there is Apple passkeys. Why are there 2 different new things going around and which one is going to be the main or better long term choice? Obviously having a security key is nice since its not storing anything online. It’s completely local to your “key”. Lastly how many devices or things will 1 security key work with and if it’s only one device these will not be great at all since if you have several hundred websites to log into you would spend a fortune to have security for all your log ins. Thanks for your video and we hope you have to to reply to our message here.

So…if someone steals your backpack where inside you have your iPhone and a security key what then?

[@street55789]

I can’t imagine having to do this 25, times a day (I lock my phone when I set it down). Plus, geez, all I need is one more thing to carry and lose.

[@InspiredInsights4U]

NFC tags come in a lot of different styles. Everything from stickers to magnets buttons is really pretty in this what they can do with the NFC technology with that in mind you could take an NFC tag and put it on your desk and that way when you’re sitting at your desk working all day all you have to do is move your phone to the appropriate spot on your desk and it would take an unlock. This could be very helpful, if the security key manufactures adopted some of these other form factors, and I think a great one would be a watch band something you wear already

[@crimlarksSteve]

Nice explanation guys.

[@ynoT_63]

I'm gonna pass on security keys. I don' t need anymore keys dangling from my keyring and I definitely don't need another thing to potentially lose. If I forget my password I can change it and access my stuff. If I understand what you just explained, losing a security key means I'd be, in physics terms, attached to another object by an inclined plane wrapped helically around an axis.

[@PeteS_1994]

What about thieves they can access your iPhone and delete everything

[@georgewashington3012]

You set up two keys - one that you may keep on you and one you keep securely stored elsewhere like a safe or safe deposit box. Apple actually requires the setup of two for this reason.

If someone watches you put your passcode in and then steals your phone, they will steal your money from your bank if you have your banks linked. Feel free to pass on smarter (albeit older) technology, but it's pretty cheap protection!

[@NicholasAndre1]

Those yubikey 5ci ones are notorious for exploding on key rings. I have one where all the plastic fell off. You’re definitely better off going USB-C if your apps all support NFC. I’ve had pretty good durability with the USB-A ones from Yubikey; the usb c connectors definitely take less torque than the usb c ones.

[@Bushchannel]

Yubikeys are known to be the toughest. I heard a story of a yubikey that was stuck in a washing machine for months and still works.

[@VitoAD]

I have the YubiKey 5Ci and what I was make a holder with a clip out of paracord. Just clip it on my key chain and it solves the issues you mention. I also keep a USB C to USB a adapter connected to the yubikey.

Whoops ! you are comparing incorrectly; Yubikey basic is $25, the 5 series is advanced for future growth in compatibilities. I do think that a good lower cost key is ample to carry for a phone, but a more advanced key seems desirable for laptop and desktop / and future security developments.

Maybe it’s something to be used while traveling or at bigger meetings/conferences mainly? I’m a healthcare provider and this could provide patients with more security around their medical data.

[@PayetteForward]

The key is made my Google, but it isn't in any way linked to a Google account or the internet at all, and that's true for all of the keys we recommend. The only tech inside is a little NFC chip that has a secret code that gets sent back and forth between the iPhone and the key itself. It's not that we think Google is bad with privacy - they actually have a lot of great options - we just think the default Google account settings give away a little more personalized information than some people would feel comfortable with. How's that for a diplomatic response?

[@chrisbaier6252]

So, if I understand this, you don't need the key to just log into your phone (you just use your PW/FaceID) its only when you log into your Apple Account. (as a second-factor of authorization), right? So if someone got your phone and PW, they can't change your AppleID PW. This is great if you lose your phone, but if someone robs you, they will take your phone and keys (and security key). Seems like Apple could incorporate this into AirTags and/or Apple Watches, to use them as keys (need to enter your watch password on your watch, and the AirTag has to be very close to the phone, or print a QR code on the back that you can scan with non-NFC devices). I literally just took all my keys off my key ring because I hate the bulk. (my house has a keypad lock). So i just have my car keyfob and AirTag.

I appriciate the video demonstrating and showing how to setup, but I'm still not understanding how you use them once they are setup. Purchases through app store don't trigger 2FA do they? The only thing I can think of that triggers 2FA for my apple id, is when I sign into my id on a new device, and I think the last time I needed to do that, it just asked me to hold my existing phone in close proximity to it (I assume because it was using Bluetooth). I suppose logging into apple id on computer would trigger 2FA.. Right? So once the keys are setup in iOS, that still wouldn't protect any of your other accounts besides your Apple ID, right? I'm very interested in using these, I'm just not understanding the whole work flow Another thing for people to keep in mind is that the iPads don't have Nfc scanners, so they will need to pick keys with the right type of connection for their device

Question: Apple says you can be locked out of your account if you loose both configured keys. In settings you can remove them freely. So , if you loose both keys can you just remove them to take control of your account or does iOS ask for security key to remove the keys?

[@FrazzleCat]

On most accounts, I don't know if this is true for apple, you typically get some kind of recovery key (a series of numbers, or some such) that can act as a back up. If you lose your key(s) then you can use the backup code to get into the account and remove them. However, without such a code, no, you would not be able to get into the account to remove the keys. Being able to get into the account (without an emergency backup code) would defeat the existence of the keys.

You can share keys, yes. Keys aren't a replacement for passwords at this point - you'll still need to know them - but they're a step in that direction. At this point, they're a replacement for the six-digit two-factor authentication codes that you have to enter when you set up a new device. (So you won't be using these keys all that much.) With regard to third-party apps, we'll see how that shakes out.

Those are not the only people who might want to use them. I would be wiling to buy one myself. I would just save up for the NFC and fingerprint option.

Hmm looks like a new airtag upgrade coming with all bells whistles

[@FreddyMorales]

I’m not sure to install security key. What happens if I loose or damage the key . It’s a very big problem.

[@clynn3813]

Why aren’t any of these covered so the plug in part has less chance of being damaged? I wouldn’t use it on a key ring

Those keys can be stolen or lost too, beside having another thing to worry about.

In Chicago, armed robberies (and car jackings) are increasing significantly. Considering the scenario of a robber, (1) stealing your phone, (2) taking all your personal belongings (including your keys and security key), (3) stealing your car, and (4) demanding that you divulge your phone password (under threat of physical violence), then how does the security key provide protection?

[@mitchcalmes670]

This is new to me, and there was never any explanation or demonstration as to how they actually work and why do I need one???? What has brought this on?

[@MGA19a]

But … why do we need those in first place / what’s the point actually (did i miss that) - if i use 2FA !?

Great, now that we’re moving away from keys; Wi-Fi enabled deadbolts, Wi-Fi garage door openers, keyless ignition on our cars, apparently the n manufacturer lobby felt the need to have us still carry something. 😀. Seriously though, D&D, a great report.

[@southwest7977]

I’m not sure that I understand the implications of the security key. Do I need to use it every time I unlock my phone? Or just using my Apple ID. Sounds obnoxious.

[@danrodrigues3531]

Am I to understand correctly that I have to purchase two of these $35 security keys?
