Accessing Horizon

Any Wikimedia developer account holder with the 'projectadmin' role in a project has login access to The username, password, and two-factor authentication code are the ones associated with your developer account. Normal Toolforge and Cloud VPS project members can ignore Horizon for now, and possibly forever.

Horizon login requires 2FA

Horizon login requires a password and a second factor, the two-factor authentication code token. These credentials are shared with your developer account.

If you do not already have two-factor authentication (2fa) enabled for your developer account you can do so by visiting 'Preferences->User Profile' and clicking 'Enable two-factor authentication'.

Make sure you have a working SSH login to Cloud VPS before you enable 2FA. This will be helpful if you lose your back-up codes and need to retrieve them.

Retrieving back-up codes

To retrieve lost back-up codes, you will need to verify your identity with the Cloud Services Team.

  1. Contact Cloud Services Team
  2. You will be provided with instructions to verify your identity
  3. Once this is done Cloud Services Team will turn off 2fa for your developer account so you can re-enable it and reset your code
