The UX when a user changes their password is reduced due to the way the password matching is performed. The user needs to double tap the enter key or click away from the input box in order to next click the "Update" button.
Steps to reproduce:
1) Login to the XUI as a user
2) Click on the "Password" tab
3) Enter a new password in the "New password" field
4) Enter the same new password into the "Confirm new password" field
The "Update" button becomes active
The "Update" button does not become active. A enter key or click away is required to active the button.
