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.
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).
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.
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?
