Hello @EdwardB156 (Ann),
You can set up multiple users in Standard or Premium (and legacy) plans. After setting up a new user, they’ll be prompted to select the MFA method they prefer during their login creation. If for some reason you're finding that your account isn't allowing the maximum number of users for its level, please call our Billing team so they can check our backend for any antiquated settings.
