Two-factor authentication (2FA) adds a second verification step to Hosting Portal login. After enabling it, each login requires a six-digit one-time code from Google Authenticator in addition to the standard credentials.

​
Enable two-factor authentication

  1. Log in to the Gcore Hosting Portal.
  2. In the Client section of the sidebar, click User settings.
  3. Navigate to the Two-factor authentication section and click Enable two-factor authentication.

If the QR code cannot be read, enter the value from the Key field manually into the app. The key is regenerated each time the setup form opens — if QR code or key files were saved previously, download fresh copies using the Save QR-code and Save key links on the form.
  1. In the Temporary password field, enter the six-digit code generated by the app.
The code is time-based. Verify that the time and time zone on the phone match the Server time shown on the form. A difference greater than one minute causes the code to be rejected.
  1. Click Ok.
