Two-factor authentication (2FA) is a critical security feature used to protect your online accounts and data from unauthorized access. It requires users to provide two distinct authentication factors to gain access to an online account or system. It adds an extra layer of security beyond just a username and password, making it significantly harder for cybercriminals to compromise your accounts.

2FA is a security process that falls into 3 categories. They are,


  • Knowledge Factor is usually your password, a PIN, or an answer to a security question.

  • Possession Factors such as a smartphone, a hardware 

  • Biometric Factors like your fingerprint, retina scan, or facial recognition.
 
Benefits:


  •  Enhances Security

  •  Protecting Against Phishing

  • Securing Sensitive Data

  • Preventing Unauthorized Access
