2 Factor Auth alternative


Can I use others 2 factor auth for loging into sunstone UI like FreeOTP+ or andOTP available on F-Droid ?

I haven’t actually set up MFA with Sunstone, but those – and at least some other f-droid OTP packages – are compatible with google authenticator, for instance. They just implement the TOTP or HOTP standards (which don’t defeat phishing like u2f/fido2, but can be used more generally).
