If you turn on Federation in Gitea app.ini settings then WebFinger will work. Nothing else is currently implemented.

There is also a authy-export tool that makes it pretty easy to export all the tokens to selfhosted pass repo.

Maybe a bit different but I quite like WikiJS https://js.wiki/

I have it setup to use PostgreSQL and its built in text search engine and every page is also saved into a git repository.

I have quite a lot of notes written there over the years and im pretty happy with it.

ProFont looks quite nice, pretty similar to Terminus Font that I usually use in terminals.
