What is Salesforce Authenticator?
The Salesforce Authenticator mobile app is a strong verification method that can serve as a second factor for MFA logins. The app is free and simple to use, minimizing the impact of MFA on the user experience.
Salesforce Authenticator makes the extra MFA authentication step easy through push notifications and location based automation.
Setting up a PIN or biometric requirement on your mobile device is highly recommended. This extra requirement ensures that unauthorized parties aren’t able to access Salesforce Authenticator. See Salesforce Authenticator for setup instructions.
