Since it is recommended to change passwords every now and then, and even users who are not forced to do so due to policies should take this to mind, there is an option to change the passwords or the user and the associated password.
Important: User name and password must always be entered, only the entry of the possibly changed user, or the changed password alone, will be accepted, but the connection will not be successfully established due to the missing data.
Exception: If the user with the associated password has the release for the relevant path. For example in a domain network.
