User and Administrator Identification
By default, some menu options are protected by privilege levels: user and administrator, each with its own pass-
word. You can also customize the access permission for the configurations on the web user interface and phone
user interface. Yealink phones support the access levels of admin, var, and user.
When logging into the web user interface or access advanced settings on the phone, as an administrator, you need
an administrator password to access various menu options. The default username and password for administrator
is “admin”. Both you and the user can log into the web user interface, and you will see all of the user options. The
default username and password for the user is “user”.
For security reasons, you should change the default user or administrator password as soon as possible. Since
advanced menu options are strictly used by the administrator, users can configure them only if they have admin-
istrator privileges.
