Grokio's apps should support TOTP (2FA)
Due to the nature of Grokio's offerings, the platform should support two-factor authentication. A breach of a user's password (for whatever reason, including their own incompetence) may be more than a mere inconvenience due to social stigmas.
The most interoperable and common form of 2FA these days is TOTP. It's more commonly seen in the guise of Google Authenticator and a bajillion more... even many password managers will automatically copy your TOTP token to your clipboard after auto-filling your credentials these days.
It would be a great optional feature for users to enable, enabling more trust in the platform. And it would be something that would be easily worked into a login workflow for both web and mobile.
