What is two-factor authentication (2FA) in cybersecurity?
- A method of verifying identity using two factors
- A password manager
- Multi-factor authentication
- Single-factor authentication
Two-factor authentication involves using two independent factors to verify identity. This typically includes something you know (like a password) and something you have (like a mobile device). Unlike single-factor authentication, which relies on just one factor, 2FA provides an additional layer of security, making it harder for unauthorized individuals to gain access. Understanding this is crucial for implementing robust authentication mechanisms.__________________________________________________
