If you want to enable two-step for FTP access check Enable two-step verification for FTP connections.


If you enable this option configure your FTP client to send the password in the following format: YourPassword#GeneratedToken


If your software has scanning capabilities you can scan the QR-code.

  • Generate a token and type it in the "Generated Token" field.
  • Click on Save.

Common Errors

The token is generated based on the current time and is valid for 30 seconds. This required that both the client and server have the correct time.
