Multi-Factor Authentication (MFA) for Single Sign-On (SSO)
With single sign-on (SSO), users log in to Salesforce from another site, like Google (the SSO provider). To secure these logins, Salesforce requires users to prove their identity with multi-factor authentication (MFA). You can satisfy MFA requirements by using your SSO provider's MFA service, provided that your SSO provider sends the right authentication signals to Salesforce. Alternatively, you can use the MFA functionality provided by Salesforce.
