MR6550 Mobile App

if left on default, it should be on the label at the back of the device. Otherwise, it's whatever you changed it to be.

The MR6550 default admin username is admin and the default admin password is printed on the device label (inside the battery compartment). On many models the default is just password. If that doesn’t work, do a factory reset to restore the defaults, then log in and set a new password.
