If the administrator chose Google Authenticator while enabling two-factor authentication (2FA), you should follow these steps to set up 2FA:
Download Google Authenticator app on your device (open a relevant app store and search for and download Google Authenticator app)
Set up your account in Google Authenticator app (enter your account name and key). Google Authenticator app will now generate a new 6 digit passcode every 30 seconds. You should use this to complete your 2FA setup process and when you log in to FTP-Stream in future.
Log in to your FTP-Stream account
If the administrator shared the link for passwordless login, skip this step.
Scan the barcode with your device or enter the key below
Enter 6-digit 2FA code from your device
Click the Proceed button
After clicking the Proceed button you can use your FTP-Stream account.
