Hey Michael,
Thanks for the question. As @Phil_Seeman mentioned above, Asana’s events are powered by Bevy 
We use the Bevy platform to host events and give folks a simple way to RSVP and receive important updates through their Asana login. By logging in through Asana SSO, the person will be prompted to authorize the platform to grab a name and email address for the account. If you’d rather not use your Asana account to login, that’s okay too! You can easily create an events account by visiting Trainings, webinars, in-person events, and more! | Attend Asana events, clicking “Login” in the upper right corner of the screen, and then select “Create Account”.
I hope this helps! Let me know if you have any additional questions.
