2 options here.
Easiest: The sip software/device should only need to be configured once
no matter what IP address it is on and will login itself. So no need to
remember new password.

Harder but not really that hard: Lock down your asterisk ports with
linux firewall capabilities and when your app logs the user in, it
applies a rule allowing that user into the aterisk machine. Of course if
you plan to route calls to the user, they need to have at least a
username configured to the sip device so it can identify the user.
