Changing the Admin Password
Cisco Unified CallManager 4.1 or Later
If you are running Cisco Unified CallManager 4.1 or later, you can use the Change
Password area on the web page to change the administration password for the
phone web pages.
To change the password on the web page, you must first enter the old password.
Enter the new password and then reenter the new password to confirm the change.
To display the Change Password area, access the web page for the phone as
described in the
“Accessing the Configuration Web Page for a Phone” section on

Cisco Unified CallManager 5.0 or Later
If you are running Cisco Unified CallManager 5.0 or later, you must set the
password in Cisco Unified CallManager Administration on the Phone
Configuration page. The password set in Cisco Unified CallManager takes
precedence over the password that is set on the web pages.
Caution When setting the Administration Password in the Product Specific Configuration
section in Cisco Unified CallManager 5.0 Administration, you must enable TFTP
encryption. Otherwise, the password appears in readable text in the phone
configuration file and can be viewed from any host that has access to TFTP server.
