How to Send Sign-In Links to Attendees
Learn how to send attendees a login link that lets them log into their accounts without a password.
How to Send a Sign-In Link
- Open the Check-In Tool.
- Search for and select the attendee you want to send a link to.
- Confirm their email address and phone number are correct.
- Scroll to the bottom and click Send Sign-In Link.

Troubleshooting
The Attendee Didn't Receive the Link
- Double-check that their email address and phone number are accurate in the Check-In Tool.
- Ask them to check their spam or junk folder.
- Try resending via SMS.
If they still can't receive the link, their provider may be blocking the message. In that case, ask them to log in manually using their email and password.
The Attendee Says the Link is Expired
This usually means they clicked a link from an earlier send rather than the most recent one.
- For SMS: ask them to open the most recent message, which is typically at the top of the thread.
- For email: the latest valid link is usually found at the bottom of the email thread.
