How we collect and use your data.
How do I sign in to the attendee portal?
Open the attendee portal and enter the email address you used to register for your event. You'll receive a one-time code to verify your identity — no password required.
I'm not receiving emails from the app.
Check your spam or junk folder first. If you still can't find them, email us at communications@sigmapi.org with the address you registered with and we'll help get you sorted.
How do I update my profile or registration details?
Sign in to the attendee portal and open your profile. If a field is locked, contact your event organizer or email support and we'll update it for you.
How do I check in to a session?
From the attendee portal, open the session you're attending and tap Check In. If check-in is monitored, an event staff member will scan your QR code at the door.
How do I delete my account?
You can request account deletion at any time from our Delete Account page, or by emailing communications@sigmapi.org.
