Users can join Zoom Events in the following ways:

• Zoom desktop client
• Zoom mobile client
• Web browsers
• Zoom Rooms
• PSTN/SIP devices (when the event host’s license is supported)

Zoom Events provides multiple options to ease the join across devices and platforms. Event hosts can customize join options for specified needs.

Event hosts can configure an event with required registration or with no registration. Events that require registration have an event detail page that facilitates the event introduction and the registration flow of the event. Events that do not require registration do not have an event detail page. Hosts must create join links and share the links with the target audience.

How to enable or disable registration for your event

Events that require registration

During the event creation setup, event hosts can select the Registration Required checkbox to enable registration for an event. Under Attendees will be required to authenticate at registration, hosts must select an authentication method from the dropdown menu to determine the user group that can register for the event.

An event detail page will be generated once the event is published. Hosts can share the page link for their event registration. Each registrant will receive a unique join link after the registration.

Events that do not require registration

In the event creation setup, when hosts do not select the Registration Required checkbox, no event detail page will be generated. Hosts will get a shareable group join link instead of an event detail page. Hosts can restrict the group join link by selecting the Attendees will be required to authenticate at the time of join checkbox. They must pick an authentication method from the dropdown menu to restrict access to a group join link.

When a group join link is unrestricted, attendees can use the link to join an event without being authenticated (need to provide an email address and the display names to the host).

How to use Zoom Events attendee join methods

Pre-registration

Hosts can pre-register attendees via the Manage Registrants tab. They can pre-register individual attendees or in bulk. They can use pre-registration to issue unique join links to specified attendees or invite them to register.

When hosts send a join invitation, pre-registered attendees will be taken into the event lobby directly. When hosts send a registration invitation, pre-registered attendees will be taken to a registration form to complete registration.

Join links

Join links open an event on web browsers or the Zoom client. Join links could be unique or shareable. Events that require registration will issue a unique join link to each registrant. Events that don’t require registration will generate a shareable group join link.

A join link could be restricted or unrestricted. When a join link is restricted, attendees will be taken to a sign-in page to complete authentication. The sign-in page is subject to the configuration of the authentication profile chosen by the host. For example, the host could choose for attendees to sign in to Zoom or sign in to a specified IDP. When a join link is unrestricted, attendees will not be authenticated upon joining the event.

Meeting ID and passcode

Meeting ID and passcode make joining an event on Zoom Rooms, a PSTN/SIP device, the Zoom client, and zoom.us possible. The meeting ID and passcode are generated automatically with join links.

Attendees can join a single-session event using a meeting ID and a passcode. The meeting ID is the same across all attendee roles and special roles. Special role users and registered attendees will receive unique passcodes. Attendees of a group join link will share the same passcode. The meeting ID and passcode are available in the registration confirmation email, in the attendee’s calendar, and in the More menu of the session card in the event lobby.

Attendees can join each session of a multiple sessions event using a meeting ID and a passcode. The meeting ID of each session is unique. Both attendees and special roles use the same meeting ID when they join the same session while the passcode is unique. The meeting ID and passcode are available in the session card's More menu  in the event lobby.

Auto Join

In some cases, attendees will join a session automatically. If attendees join a Zoom single-session event’s lobby before the session starts, a message will inform them that they have been enlisted in an auto-join queue, and they will be taken into the session automatically once it starts. Attendees can choose to remain in the auto-join queue or leave the list.

Direct Join

Direct join is an option for hosts to bring a special role into a session. Direct join is not restricted by any authentication methods. It directs the user to a specified session instead of the event lobby. Direct join is available in the Special Roles tab within 30 days before an event.

The host can create the link by providing the email address of the speaker. An email containing the direct join link will be distributed to the email address immediately. Learn more about inviting speakers with a direct join link.

How to understand authentication methods

Zoom Events provides a set of authentication options:

• Sign in with Zoom or authenticate over email OTP: Users must sign in to their Zoom accounts for authentication or provide a valid email address to receive a one-time password (OTP). This also helps guests without Zoom accounts to join an event.
• Sign in with Zoom: Users must sign in to their Zoom accounts for authentication. They must have a Zoom account when this method is enabled.
• Sign in with an external SSO: Users must sign in to the IDP specified by the external SSO profile. They must belong to the group of an external SSO.
• No authentication: Users must provide their email address, first name, and last name upon joining. No sign-in is required.

Hosts can select the Apply Allow List checkbox to apply restrictions on top of an authentication method. An allow list can include allowed email domains or specified email addresses. Attendees must pass authentication and match the allow list before joining.

Additional authentication

Hosts can apply additional authentication to their events. An additional authentication step will occur when attendees join.

• Security at Join: Zoom users require additional authentication through a security code. This will initiate an email OTP verification after attendees pass authentication and match the allow list.
• Zoom users: require additional authentication through a security code: This option requires attendees to authenticate and initiates an email OTP verification to attendees who registered via email OTP. Attendees will be required to confirm a one-time password after authenticating when joining.
