Hi folks! Today I have asked myself if I could login with one (no, not google or apple or micosoft) account in all the (30 I think) forums that I have to use as a FOSS admin. Nextcloud Forum, Ubuntu Forum, Mint forum, Makemkv Forum, Papermc Forum, linux.org, etc.

We obviously are on a forum-like social platform but we cant make people use this as their forum I suppose. Ideally, I'd like to federate "all forums" so to speak but that would probably take a shit ton of work. https://socialhub.activitypub.rocks/t/does-this-forum-use-activitypub/2545/2

If not federate the content, maybe federate the logins. So that the profiles federate from one place to the next and you can login anywhere without having 30 different passwords for one "service" (forum in this case).

The next step down would be a foss SSO solution. There seem to be some but I hardly see any pages mention them possibility at all. https://sennovate.com/best-open-source-single-sign-on-solutions/

Am I missing something or is this still in the distant future?

Thanks for reading. Have a good one.

It's called private/public key pair. If you give the public key to a website, they can let you in as long as you have the private key to encrypt a message that matches the pubic key.

As such, your public key is safe to share and you can always verify yourself as the owner of the private key if you have it.

SSH log in works like this.

I mean, I use this for github and my servers but I never had the idea to use this for login purposes! Thats pretty awesone. Any idea if that is possible to use somewhere?

Yes, it's called passkeys aka WebAuthn and it's in the process of being widely implemented everywhere.
