SSO is widely used across B2B & B2C platforms now and we're falling behind on the trend. It make's it faster to register but also more secure when entering an auditorium. I've just lost a prospect as we aren't secure enough to restrict people accessing the auditorium, i.e. people can use someone elses email to enter. The unique access code isn't effective either, it's essentially just having another email field. We're asked if URLs can be made unique to an attendee/email too.
