Just like apps and websites implement “Sign in with Apple” and Google couldn’t we build some kind of federated authentication provider? Then everyone creates an account there and fedi apps can implement an easy way to authenticate users. Even non fedi apps could use it. I imagine user interaction between different fediverse platforms would be much easier too.
I guess could run an auth instance. Ideally everyone would run their own, keeping your data safe.
Is there something likes this already? Saw some discussion here but not much else https://socialhub.activitypub.rocks/t/single-sign-on-for-fediverse/712
please correct me if i’m wrong on this. lots of people here saying that it’s not practical because we would have to trust tiny instances that may be malicious. however, what if we make user’s identity provable to anyone, simply by the use of logic? suppose we have a way of generating random proof-theorem pairs (for example, the theorems could be something like “the largest proper factor of n is greater than some m, where m and n are some huuuuuge numbers and n is semiprime”, the proofs could be constructive). we let the identity be the theorem and the password be the proof. hence, anyone is able to verify the indentity by the use of a theorem prover like Agda
Congrats you just invented passkeys
why can’t we use passkeys instead of passwords though? is it just a matter of convenience? if so, maybe there is a way to determine a passkey from a password?
