Currently, IRIS has two options for 2-factor authentication. You can use SMS, which requires a cell phone, or you can use an authenticator app. This is also generally going to require a cell phone. I would be helpful for some of our users if we could implement a 2FA that just emails a one-time code to the user so they can enable 2FA without requiring all of their users to have their cell phone available.
Thank you for submitting the idea. The status has been changed to "Needs review".
Stay tuned!
