Multi-Factor Authentication: Enhancing Online Security

Understanding Multi-Factor Authentication

Multi-factor authentication (MFA) adds an extra layer of security beyond just a username and password.

The Two-Factor Process

With MFA, the process typically involves:

  • Username and Password: Initial login credentials.
  • Authentication Code: Second-level verification, often via a unique code.

Methods of Authentication

MFA utilizes different methods to generate authentication codes:

  • Text Message: A unique code sent to your mobile phone.
  • Authentication App: An app generates time-sensitive codes.

Text Message Verification

Text message verification commonly involves:

  • Code Delivery: Receive a code via text message.
  • Code Entry: Enter the code on the website for authentication.

Authentication App

An authentication app:

  • Generates Time-Sensitive Codes: Codes change periodically, enhancing security.
  • Short Time Window: Users have a limited time to enter the code, typically around 30 seconds.

Benefits of Multi-Factor Authentication

MFA offers several advantages:

  • Enhanced Security: Provides an additional layer of defence against unauthorized access.
  • Reduced Risk of Fraud: Increases the difficulty for hackers to compromise accounts.
