The 2FA Login plugin enables applications built with Backendless to provide an authentication option where a user can login using the TOTP (Time-based One Time Password) form of two-factor authentication (2FA). With this approach, users of your Backenless-powered app can use TOTP mobile apps such as Google Authenticator or Twilio’s Authy apps to login without a password. The 2FA Logic plugin introduces a workflow with the APIs to coordinate the login process. See the information below on installing the plugin and using its APIs.
