What is meant by Two-factor authentication?
Two-Factor Authentication (2FA) is a security mechanism used to protect access to an account or application. It requires two different methods to confirm a user's identity, instead of just using a password. Typically, these methods include something the user knows (like a password) and something the user possesses (like a smartphone or a hardware token).
Typical features of software in the realm of Two-Factor Authentication include:
- Support for various authentication methods: The software provides a range of methods for the second factor, such as SMS codes, mobile authentication apps (like Google Authenticator or Authy), biometric features (e.g., fingerprint or face recognition), hardware tokens, or emails.
- Integration with existing systems: The software can seamlessly integrate with existing applications, websites, or networks to ensure a smooth authentication experience.
- Administrative controls: Administrators can enable Two-Factor Authentication for user groups, set policies, and utilize monitoring and reporting features to monitor system security.
