Having TOTP tokens stored alongside passwords kind of defeats the purpose of two-factor-authentication. I think this alone justifies development of a separate app, but there must be other reasons as well.
Deffo a tradeoff. But then my bitwarden account is secured with a long phasephrase, and MFA (with offline recovery codes), with the TOTP in Google Authenticator.
Its a tradeoff, but on balance, i am happy to keep my TOTP for accounts secured by bitwarden inside bitwarden.
