# Two-factor authentication (2FA)

Two-factor authentication adds an extra layer of security by requiring two different types of verification before granting access to an account, combining multiple authentication methods to create a more robust security system that provides greater peace of mind.

For certain account types, transactions, and jurisdictions, multi-factor authentication (MFA) may be required as part of regulatory or compliance requirements. This includes some state-specific requirements, as well as transactions associated with FNF (Fidelity National Financial).
