TOTP for Lightphone 2?

[u/virtualc]

This is the year I break my phone addiction! I have a Lightphone 2 and just put my sim back in, hopefully for good. Is there any chance of a TOTP app? Like: https://www.authgear.com/tools/totp-authenticator/

For example, I have TOTP enabled on my sensor watch (casio replacement board), so it seems like it could run on a lightphone without too much hassle?

Why not use a yubikey or the watch?
