The default user name for the Verizon 9100VM router is "admin" and the default password is "password." Do not enter the quotation marks.
Note: To improve security, your router password may have been changed to the serial number of your Verizon 9100 router if you hadn't previously changed the password from the default of "password." You can find your router's serial number on the label affixed to the bottom or back of your router.
If you reset your router to the factory default settings, the router password will return to "password."
The user name and password are case-sensitive, so be sure to enter them in lower case.
