Secure authentication for EVERYTHING! // Authentik

In this KZbin video, we’ll cover authentik, an open-source identity provider that allows for secure login to administrative services and web applications. With this setup, users only need to sign in once and can access all their services without having to log in multiple times. This not only saves time, but also increases security with multi-factor authentication. I also demonstrate how to install and set up authentik in your own environment.

I want to add a comment that I hope you can see as being constructive since you mentioned in a previous video that English is not your first language and that you are sometimes concerned about your pronunciation or word choice. As an American who barely speaks a little bit of a couple of other languages, I have always appreciated when people helped guide me so hopefully I can do that this one time for you. The word realm is pronounced like helm. Thanks for the awesome video!

[@NOBODY-oq1xr]

you mean like "helm" but with an "r" :D just saying this to make sure nobody is wondering why the realm would be pronounced helm :D

Hi, I don't know if it's just me or not, but I think you should explain what "frontend" and "backend" networks are. Because at the beginning (from you past videos) I thought they were some kind of docker built-in networks (due to having a very specific and standard name), but with time I realized that they are just two network you created. So maybe you should clarify what those networks are and why you use them the way you do. At least for beginners, it's not that obvious.

[@utentepassivo]

I very much agree with this. For beginners like me it can be very confusing

[@boosraphael]

Hello sir, thinking about your Netbird tutorial have you thought about the advanced installation that allows you to use Authentic as the IdP? I am still continuing that journey as I need to work on alternate ports to use as the one out of the box are already consumed.

[@SMAW04]

Great video again Christian.. I Also noticed the cool keyboard on your desk, wanna share which one it is?

This looks great for a homelab, I just doubt it can fully compete with capabilities of the hybrid Active Directory I run at work.

If you already have cloudlfare setup on your domain, it also gives you similar setup. Easy to configure as well.

[@cooptonian]

Hey, awesome video!

Hey, thanks!

[@badtrapify]

I tried to integrate proxmox. Created an OpenID provider, created an application, using this provider... Set the realm in proxmox, aaand... When i select my authentic realm for login in proxmox the OepnID redirect fails. "remote error: tls: unknown certificate authority" I guess it's something with the self signed authentik cert, but don't know how to avoid it.

[@Voigt_Analytics]

Ziemlich cool. Danke für das tolle Video! Es fällt allerdings in die Kategorie: "Nice to have". Da (m)ein Home Lab dem ständigen Wandel unterlegen ist, weiß ich nicht, ob das für mich wirklich Sinn macht. Vieles an Software ist allenfalls ein paar Monate oder ein halbes Jahr an laufen, bis ich auf die Idee komme, Systeme wieder neu aufzusetzen, die Software neu einzurichten und dann muss ich trotzdem ein Passwort-Manager haben, der mir die Admin-User abgesichert. Es wird nur zusätzliche Arbeit verursacht durch die doppelte Nutzerverwaltung. Das hat sehr viel mehr Sinn in Unternehmensumgebungen, wo IT-Abteilungen auch von frustrierten Mitarbeitern besetzt sind, denen man im Fall des Falles immer auf die Finger schauen/klopfen muss. Oder um Mitarbeiter zentral zu verwalten, was wiederum durchweg Anwendungen voraussetzt, die die genannten Auth-Provider unterstützt. Und Authentik darf bloß nicht kompromittiert werden oder ausfallen. Dann wird's lustig

[@timothypierce4602]

Ay ay apoco si?

[@christianlempa]

Vielen Dank :) vielleicht macht es ja Sinn für System, die du nicht häufig änderst wie z.B. Proxmox?

[@Voigt_Analytics]

@@christianlempa Dieses System muss erst noch erfunden werden 😅 Nein, Proxmox nutze ich nicht. Versuche so stromsparend wie möglich mein Home Lab zu gestalten, daher kommen derzeit nur zwei Raspi‘s 400 und ein MacBook Air 2019 zur Anwendung. Das MBA für etwas performantere Aufgaben. Vielleicht wäre auch das Thema Energiemanagement, Shelly‘s, Grafana und Co was für die nächsten Videos? 😃👍

@@christianlempa Habe meine Meinung geändert. Die Software ist echt genial. 🤩 Allerdings stehe ich noch vor einigen Problemen mit bestimmten Softwarelösungen.

Hi there, great video. I recently saw your video on how you set up your vscode, but is there any chance you could share what theme/customizations you are using? I really like the transparent and clean look yours has but I didn't see it in that video.

[@christianlempa]

I'm using my own theme "The Digital Life", hope to give it an update at some point

[@Taterxxwardy]

I was also very confused by their documentation and trial and error with it so far. I've tried Jim's Garage and others but they seem to do things a bit different from what you do, which is more like my server setup as well. Appreciate your insight and guidiance

[@christianlempa]

Thank you :) glad you liked my video more

[@christianlempa]

Thank you! Hope you will find it useful

[@wiadrovit]

@@christianlempa So I did it and it was something I should have done long ago. I trusted your gut and replaced my good old nginx with traefik as well. I was a bit hesitant at first, but it is really cool and it gets even more awesome when you figure out how it works. As for authentitk, I still have a couple of apps to configure but those I already took care of are working just great. Thanks a ton Christian! Keep the great stuff up!

[@GuilhermeMarquesMachado]

how would you use this with Obsidian's docker container?

[@Paul-xb5mm]

Hi, did you manage to setup login to Sophos with authentik? I tried using LDAP for a while but unfortunately couldn't do it. Maybe I can learn from your experiences later. :D

[@christianlempa]

Not yet, but I'm currently looking into it! There will be a follow up video at some point :)

[@efimov90]

@christianlempa, is it possible to use authentik with mariadb? How i can see there is ldap provider and mariadb has ldap authentication support. Is there a posibility to use OAuth or only this option is available now?

[@PeterBuffon]

Strangely i'm getting this weird behavior where i can reach the login page, but when i enter my email and go to put the password, the whole page HTML outputs on the page and idk what to do.

[@andreassa]

Personally, I haven’t found anything easier to setup than Caddy + Authelia for my small homelab (plus custom Tailscale domain login). I will give this a go some other time! Thank you

[@christianlempa]

You’re welcome! Let’s us know if you like it

[@gggkiller]

You can actually rename the default user, but you have to do so through the Directory interface, it's what I've done in my install. Other than that, great video and thank you!

[@christianlempa]

Thanks for the tip!

[@Seba11PL]

Nice vid. I thought you would make a video about Zitadel, which you mentioned in a previous video. Authentik seems fine, but Zitadel appears more modern and supports passkeys.

[@christianlempa]

I had a couple of issues with Zitadel, and to me, authentik seems better. Maybe I'll take a look at some point

Amazing explanation for this great app! I've already set it up on my Kubernetes cluster and it is working great so far and I'm satisfied with it, but there is some work to be done, and the documentation is patchy in places. I noticed one more drawback which is that it starts up slowly. Perhaps it is due to the fact that it was built with Python (Django?), but not 100% sure. I can live with that.

[@christianlempa]

Great to hear!Thank you :)

I've tried doing this but somehow can't get it to work. I'm trying to connect authentik and portainer. After adding a provider and a application I've tried to login to portainer using oauth. I get the portainer error "Failure Unauthorized" and a little "unable to login via oauth". I've also noticed that my user wasn't automatically created in portainer. But even after manually adding it (it states oauth in users) I get the same errors. Any idea?

Just wondering if you have some tips on how i can add authentik to the home page? the documentation is skinny on the process...... cant say this enough...you make sure informative videos!

@@christianlempa I did use your GitHub as a reference ... I think the generation of the authentik key .. it's not very clear on the steps to take

Awesome video , thank you! Btw , when you have docker or docker compose env variables and you want to name your container env variables the same as you want them set in your shell , you don't need to say i.e. MY_SUPER_VAR=$MY_SUPER_VAR ... you can just have - MY_SUPER_VAR and docker will pick up your shell variable with the same name if it's set for example services: test: image: nginx environment: - MY_TEST_VAR instead of services: test: image: nginx environment: - MY_TEST_VAR=$MY_TEST_VAR

[@christianlempa]

Thanks! :D Good tip

[@alex.prodigy]

@@christianlempa it also works with .env file or other env_file

[@christianlempa]

@@alex.prodigy one reason though I might keep using the scheme is interpolation of environment variables, to catch errors or apply default values. which makes it easier for the tutorials and boilerplates.

[@alex.prodigy]

​@@christianlempa yep , no worries ... just figured many people don't know that docker compose can pick up env vars without doing MY_ENV_VAR=$MY_ENV_VAR

You did a video on Dockge at one point. Is there a reason you didn't use it in this tutorial? This isn't criticism, I'm genuinely curious. Do you yourself simply not need it or are you just lowering the barrier for entry with Authentik? Great video as always, sir! 🙂

[@christianlempa]

Actually, I'm not using it because I prefer using vscode for managing my containers. I also believe it's better for the tutorials to not rely on too many apps that some people might have, some others don't.

Hi Christian ! You are great and I have to say a big thanks to you... I just installed Authentik in my lab and setting up all the appliances and servers ... every night 'till 4 o'clock ... :D :D :D . But I have also a question ( or suggestion request for you ) : How did you managed the authentication on each node of a proxmox cluster ? Probably i'm too newbie on this but the right way should be : 1 provider ( with all the keys ) and more applications ( 1 x each node ) ... but is not possible , and is also not possible to have more tha one provider for the same Proxmox datacenter ... ( if i'm not wrong ! ). Do you already have the answer : have you already managed this ? Anyway : many thanks ! A lot !!! bye !
