UC documentation question regarding reg.1.auth.password

On page 87 of the most recent UC documentation is states:

You can change the default password using any of the following methods:
• The popup prompt when the phone first registers
• Phone menu
• Web Configuration Utility
• Use the parameter reg.1.auth.password in the template configuration file

It this last bullet point correct? I thought reg.1.auth.password  was the password used to authenticate with the SIP and not the phones local admin password.
