Authentication profiles initially need to be enabled for all members of your account while you configure the profiles. The Only authenticated users can join meetings option requires participants to sign in before they can join a Zoom meeting. This can be useful if you want to restrict your participant list to verified users or users from a certain organization.

Once the profiles are configured, you can disable this setting at the account level if you do not want it to apply for all members of your account.

Note: If a participant does not have a Zoom account, they will not be able to join the meeting or webinar if this setting is enabled.

How to use Meeting Authentication Options

Account owners and admins can choose if they want to make changes to Meeting Authentication Options. Authentication configuration is useful when you want to invite only verified participants from trusted domains. It also secures meetings that include participants from different organizations. Account owners and admins can select the following authentication methods:

• Signed-in users in my account: Allows any signed-in user in the account to join the meeting or webinar.
• Sign in to Zoom with specified domain: Allows you to specify the rule so that Zoom users, whose email addresses contain a certain domain, can join the meeting or webinar. You can either add multiple domains, using a comma in between and/or use a wildcard for listing domains. You can also upload a CSV file with the domains.
• Sign in to external Single Sign-On (SSO): Allows you to specify a rule so that users need to authenticate through a 3rd-party authentication service.

Note: Meeting Authentication Options will apply to meetings after enabling Only authenticated users can join meetings.

Configure Meeting Authentication Options

1. Enable Only authenticated users can join meetings at the account or group level.
2. By Meeting Authentication Options, click Add Configuration.
3. Under Give a name for users to know this authentication, type a name for the meeting’s authentication method to help users identify it.
4. Select an authentication method from the dropdown menu.
5. Complete the required fields as needed.
