My only complaint with jerboa is that it keeps forgetting my login details.
I use a password manager. I don't know what my lemmy password is. I just know it's really long, so logging in requires owning up a second app, searching for lemmy, copying my password, going back to jerboa, and then going through the login flow.
KeePass2Android has a software keyboard with integration with the pass DB and it detects what app you're typing into (and websites too with browsers using the right API), and you can put the app name in the password entry to have it autofill
