2FA - Two-factor authentication Two-factor authentication , or  2FA  as it's commonly abbreviated, adds an extra step to your basic login procedure. Without 2FA, the password is your single factor of authentication: you enter your username and password, then you're done. With 2FA, you log in to the Admin Panel by entering your username and password and the six-digit code provided by an app installed on your smartphone.  After the latest update of the Admin Panel, you will be prompted to enter the 2FA code in a new pop-up window. Enable 2FA for the Admin Panel If you're using this Admin account as credentials for the API, the API login will fail after enabling 2FA. To solve this, create a Sub-Admin with special permissions for the API authentication only.  What you need: - a smartphone with a 2FA App installed (OTP / 2-Step Verification / 2-Factor Authentication), such as  Authy  or  Google Authenticator . To enable 2FA for your Admin account: Log in to the  Admin Panel From the menu, go to  Security  →  2FA Update the dropdown  Select Status  to  Enabled . Click on the  Save  button.       Recheck the requirements: have a 2FA App installed on your phone. When ready, click on the  Next  button.       Scan the QR code with the installed 2FA App and fill in the generated six-digit code in the  Challenge  input field. Click on the Save button before your token expires.       Disable 2FA for the Admin Panel To disable the 2FA for your Admin account: Log in to the  Admin Panel From the menu, go to  Security  →  2FA Update the dropdown  Select Status  to  Disabled . Click on the  Save  button.       Insert the token from your 2FA App (such as Authy or Google Authenticator) in the  Challenge  input field. Click on the Save button before the token expires.       After you see the confirmation message that the 2FA was disabled, you can delete the entry from your 2FA app.
