Select Profile to open Edit your profile.Given name and Family name are editable. Email is shown but cannot be changed here — it is the identity you sign in with.Your name is what appears wherever Studio attributes a change: the Last updated by line on a card, source or segment, the change log of a catalog entry, and the Updated by filter.
If your account has no name set, Studio opens Complete your profile instead and asks for it before you can carry on. That version of the dialog cannot be dismissed.
Passwords are not managed in Studio. Sign out and use the Forgot password link on the sign-in page, or your identity provider if your organisation signs in through one.
