Multi-factor authentication (MFA) is a means to authenticate a user. It grants them access only after presenting two or more pieces of proof to an authentication provider, including:
Multi-factor authentication asks that users provide pieces of proof from at least two different authentication categories, thereby making it more difficult for an attacker to spoof the user.
Multi-factor authentication is an important part of identity access management. It helps protect against password compromise, knowing that 81% of all data breaches involved weak or stolen credentials.
Enabling MFA with device-based challenges put a halt to different types of attacks, leading to a 100% increase of protection after using a physical key.
