How to edit user name?

[Enkhtaivan Ganbat]

Greetings,

How to edit the user name in the screenshot below? (highlighted by yellow "MSD")

The Edit button on the top right can only edit "zoljargal.e" but not the MSD which seems to be a display name

That needs to be changed in the user management system you are using for Cloud.

That's the google accounts, your SAML system or Atlassian ID (if the Atlassian ID, then the user owns the account and can change it over at id.atlassian.com)
