Two-factor authentication (2FA) is something you know and something you have.

TOTP is a time-based one-time password method of two-factor authentication.
You will need a TOTP-compatible device, such as any Android device with the FreeOTP Authenticator app. We’ll generate a QR code that you import into your device or app. After you generate the QR code, you’ll activate 2FA by entering your first activation code provided by your device or app.
When using TOTP 2FA, your password becomes your previous plain password plus a space plus the code generated by your TOTP device.
