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.
