Working with Your User Profile
As a logged-in user, selecting the icon on the right-hand side of the main toolbar to switch account menu.

The Account feature allows you to edit your First Name, Last Name and Email directly in the form, as well as change your password when using local accounts.
To change your password, fill in the required fields in the bottom half of the form: Current Password, New Password and New Password (Confirm). Your new password cannot be the same as your current password and the New Password and New Password (Confirm) fields must match.
The password change feature only works with the built-in security realm. If you are using an external security realm, like LDAP, this option will not be visible.
Only users with the nx-userschangepw privilege are able to update their passwords.
