I wonder if a system like this would be good for your general problem:

Generate a random seed sentence of so many words. From the secret seed + site domain name generate a password

Store piece of paper with:

Algorithm (could be public in github too) Seed word Site names

Wouldn't biometrics be good use case here since OP doesn't want to remember it?

Yes!! Is there a solution like that?

Yes if you can get a biometric that you can keep secret, and can easily access.

Finger prints aren't very good (they end up everywhere!). Retina scan? Not very cheap I'm guessing. Face? Definitely not secret.
