How many passwords are utilized for each user in Cisco Unity Connection?

Zero passwords would mean no authentication mechanism exists for the user, which is incorrect as Unity Connection requires credentials for both phone and web access.

A single password cannot cover both the phone PIN and web application authentication because these are separate credential types with different format requirements and access methods.

Cisco Unity Connection assigns each user a web application password used to log into the Cisco Personal Communications Assistant and web inbox, and a separate voicemail PIN used to authenticate when accessing voicemail by phone - these are two distinct credential types with independent complexity and lockout policies.

Three passwords is incorrect; Unity Connection uses exactly two credentials per user - one voicemail PIN and one web application password.
