Then IIRC I heard that andOTP wasn't that secure/maintained. Or maybe that their backup file encryption wasn't that great. I am not sure about these claims, but I migrated to Aegis, that could nicely import AndOTP tokens.
Nowadays, I use it in combination with bitwarden (it supports OTP), which I use for my less important accounts. Bitwarden (self-hosted with bitwarden-rs) allows me to generate those without my phone. I still keep every token in Aegis as well.
AndOTP features I miss with Aegis:
- Icon library for common websites using OTP
- Maybe Steam OTP support? I never used it though, since it would more or less lock me out of trading, without the app, so I use e-mail.
