Start an Audio Conference Over the Phone Without a PIN in Microsoft Teams

You can set it up so that anyone can dial in to a meeting and not be prompted for a PIN to start the meeting. You can use the admin center to enable or disable this setting for a single user.

A PIN isn't required for the meeting organizer if someone has started the meeting from the Microsoft Teams app. A PIN is only required when a meeting organizer joins their meeting over a phone. The PIN for meetings is sent to the audio user when they are assigned the Audio Conferencing license and are enabled for Audio Conferencing.
