The Application User name must  start with an alphabetic character, must be at least six characters  long and can contain alphanumeric characters, hyphens and underscores.        Administrator Account password It  is used for the login on Cisco Unified OS Administration, Disaster  Recovery System pages and Command Line Interface  (CLI) login. The  Administrator Account user name must start with an alphabetic  character, must be at least six characters long and can contain  alphanumeric characters, hyphens and underscores.        Security password It  is used by the system to authorize communications between nodes. You  must ensure that this password is identical on all nodes in the cluster. The Security password must be at least six characters long and can contain alphanumeric characters, hyphens, and underscores.     To create a strong password, follow these recommendations:   • Mix uppercase and lowercase letters. • Mix letters and numbers. • Include hyphens and underscores. • Remember that longer passwords are stronger and more secure than shorter ones.   Reset Application password on CUCM 5   To change the Application password from CLI use the command:   utils reset_ui_administrator_password     Reset Administrator and Security passwords on CUCM 5   To change the Administrator and security passwords you can use the following CLI commands:   set password admin   set password security     Note To avoid losing communications between nodes, you  must change the  Security password on all nodes in a cluster and reboot  all of the  nodes.     The systems prompts you for the old and new passwords.   If  you do not remember the Administrator and/or Security passwords, you  can follow the bellow steps in order to reset the Administrator  password. This procedure can be done with CUCM 5, CUCM 6, CUCM 7 and  CUCM 8:   Step 1 Log in to the system with the following username and password:   •Username: pwrecovery   •Password: pwreset   The Welcome to admin password reset window displays.   Step 2 Press any key to continue.   Step 3 If you have a CD or DVD in the disk drive, remove it now.   Step 4 Press any key to continue.

If you want to set up a different Administrator username and password, use the CLI command set password     Step 7 Reenter the new password. The  system checks the new password for strength. If the password does not  contain enough different characters, you get prompted to enter a new  password.   Step 8 After  the system verifies the strength of the new password, the password gets  reset, and you get prompted to press any key to exit the password reset  utility.     Note To  perform the password reset process, you must be connected to the   system through the system console, that is, you must have a keyboard  and  monitor connected to the server.
