I am using password manager, and whenever I am creating or editing users in Manager Cloud. It fills my username, which is administrator, to those profiles. Most of the times I have to log out of my password manager to edit any user but I got myself in trouble when I was creating a limiting user and it added my username and then I got stuck on that limited user privileges. Please introduce duplicate username check and restriction.
Fortunately I had administrator password too so I fixed it but why there should be multiple same usernames.
