Multi-factor authentication (MFA)
If you are looking to create a multi-layered security system for optimal security, MFA is just what you need. It aids in compliance and strengthens security. Above all, it simplifies the login process, making it user-friendly.
It is a method in which a computer user is granted access only after successfully presenting two or more pieces of evidence to an authentication mechanism: knowledge, possession, and inherence. Two-factor authentication is a type, or subset, of multi-factor authentication.
