Set the PIN length for Audio Conferencing meetings in Microsoft Teams
When you set up Audio Conferencing for Microsoft Teams, you get an Audio Conferencing bridge. A conferencing bridge can contain one or more phone numbers. The phone number you set is included on the meeting invites for the Microsoft Teams app.
The Audio Conferencing bridge answers a call for users who dial-in to a meeting using a phone. It answers the caller with voice prompts from an auto attendant and then, depending on your settings, can play notifications and ask callers to record their name.
As an admin, you can use Microsoft bridge settings to change the settings for meeting notifications and the meeting join experience. You can also set the length of the PINs that are used by meeting organizers. Meeting organizers use PINs to start meetings if they can't join the meeting using the Microsoft Teams app.

What's a PIN?
PINs can be from 4 to 12 digits; the default is 5. Numbers are only used when creating PINs. Letters and special characters aren't used.
A PIN is only required for the meeting organizer when a Microsoft Teams user doesn't start the meeting. If everyone is dialing in to the meeting, then the PIN is required for the meeting organizer to start the meeting.
PIN security settings are applied to all of the phone numbers that are associated with a Microsoft bridge. They're applied to all meetings that use the phone numbers associated with a given bridge.
Note
A PIN and a conference ID serve different purposes in a meeting. Callers use the conference ID to join the meeting and identify it. On the other hand, a meeting organizer uses a PIN to authenticate themselves and start the meeting when dialing in.

Using the Microsoft Teams admin center:
- In the navigation pane, expand Meetings > Conference Bridges.
