To avoid confusion for a user during login (i.e. forgetting the username), the default setting of the system is that during the account set-up or account registration, the username is set to the user's email address. In case the organisation login with AD/LDAP/ADFS/SSO is used, the username and email address are automatically set and updated during each login procedure. In cases of users of federated login, the username should never be updated.
Note: changing the username when using a federated login will result in either a blocked login or the creation of a new account within the system
To change the username for an account, navigate to Manage Accounts in the System Admin Panel. Find the account by entering the email address and click Change Username.
In the appeared window, input the user's new username and click Save.
Note: after updating the username, the user should be directly notified of this change
