The IntakeQ Team recommends using the Authenticator App method for your two-factor authentication as opposed to the Text Message method.
Benefits of Authenticator App method
You may use any authenticator app you wish, as long as it has the ability to scan QR codes.
You can integrate with the authenticator app even when you change devices or phone numbers.
Drawbacks of Text Message method
You are prone to carrier outages.
You may not receive messages in time due to carrier delays.
You are subject to text message charges.
Internet Access
Some users assume that text message authentication is preferable because it can function during an internet outage. However, since internet access is required to use IntakeQ/PracticeQ, this advantage does not apply.
