A Comprehensive Guide to Multi-Factor Authentication
Multi-Factor Authentication (MFA) is an electronic authentication method that grants users access to a website or application only after they successfully present two or more pieces of evidence, or "factors," to an authentication mechanism. This approach adds multiple layers of security, making it significantly harder for unauthorized individuals to gain access even if one factor, like a password, becomes compromised. Essentially, MFA is about proving you are who you say you are in more ways than one.
