When attempting to access the SBG6900-AC Web Manager for the first time, the SBG6900-AC prompts for an admin username and password. Â By default, the username is admin, and the password is password. Â For network security purposes, ARRIS recommends changing the gateway default admin user name and password after logging onto the SBG6900-AC for the first time. Â This document describes how to change the default admin username and password.
Admin Login Consideration:
- Usernames and passwords are case-sensitive.
- Passwords can contain special characters.
- Keep a record of the new admin username and password. Â
NOTE: If they are lost, a factory reset to the SBG6900-ACÂ is required to access the web manager with default admin login credentials. Â For instructions on performing a factory reset, please refer to Article # 15809Â - SBG6900-ACÂ (v1.5.x): Factory Reset.
 - Save changes made to the SBG6900-AC before changing the default admin username and password by performing a configuration backup with default admin login credentials. Â
NOTE: The backup configuration with default admin login credentials can be restored if a factory reset to the SBG6900-ACÂ is needed. Â For instructions on configuration backup, please refer to Article # 15826Â - SBG6900-ACÂ (v1.5.x): Configuration Backup and Restore Tool.Â
