Yes. Lemmy 2FA uses SHA256 TOTP digests, which are newer (and better) than the SHA1 digests used as default by most authenticator apps.
Critically, Lemmy will not have you verify that the generated TOTP code works before locking it in, nor will it give you backup codes.
You should check the documentation of your authenticator app to see if any changes need to be made in the app prior to adding Lemmy 2FA.
If your app only supports SHA1, or you fail to follow your app’s procedures to add an SHA256 digest, and you add the 2FA token generated by Lemmy, you’re not getting back into that account.
