 * All accounts created since January 2016 use the authentication from https://civicrm.org, this means that you first need to make sure that your password works on that site. If you need to change your password, you can change it there (with the [request new password](https://civicrm.org/user/password) form).
 * Make sure that your civicrm.org username does not have a space or other special characters.

+- First rename the account on civicrm.org
+- Then ask a Gitlab admin (ex: bgm) to update the "identifies" link to your Gitlab account
+
+Once that is done, you can login to Gitlab again. If Mattermost SSO is used, it will also follow.
