Strategies for Boosting Community Membership with SSO Challenges

Hi, we're preparing for our upcoming conference, vut I'm running into a challenge with driving community membership when SSO is enabled with our community platform. So when they log into our product, then they can login to the community. While SSO makes it convenient for attendees to join from their work laptops, I'm concerned that not everyone will bring a laptop or remember their login credentials. I'd love to hear your thoughts on this. Have you seen any successful strategies for encouraging community signups in a similar scenario? Any insights you can share would be greatly appreciated. Thanks in advance! Deja
