It's not clear to me what you're referring to.
If you're referring to the Member Tools app, it requires authentication to open the app. It can either be biometric or a PIN, depending on how the phone is set up. But it is required to use the app.
If you're referring to logging into websites, you may be talking about Multi-Factor Authentication (MFA). MFA is required for employee and those who have access to certain systems, such as Seminary Teachers. Others can choose to add it to their account.
