# Sign-in and 2FA

Sign in to your user profile in the Back Office using your email address and password.

If two-factor authentication (2FA) is enabled for your user profile, complete the sign-in process by entering a verification code from the Google Authenticator app.

If 2FA isn't enabled, you'll be prompted to enable TOTP (time-based one-time passwords) 2FA and will see the following message:
