Online accounts are constantly targeted by cybercriminals looking to steal personal information, access sensitive data, or commit fraud. Passwords alone are no longer enough to keep accounts secure, as attackers use various techniques such as phishing, brute force attacks, and credential stuffing to gain unauthorised access. One of the most effective ways to improve account security is by enabling multi-factor authentication.
What is multi-factor authentication (MFA)?
Multi factor authentication adds an extra layer of security by requiring users to provide two or more verification factors before accessing an account. These factors typically fall into three categories: something you know (password or PIN), something you have (a mobile device or security key), and something you are (biometric data like a fingerprint or facial recognition). Enabling MFA significantly reduces the risk of unauthorised access.
Choose an authentication method:
MFA offers different authentication options, including SMS codes, authentication apps, biometrics, and security keys. Many platforms allow users to select their preferred method based on convenience and security level. While SMS verification is common, app-based authentication or hardware security keys provide stronger protection.
Enable MFA on your accounts:
Most online services, including email providers, social media platforms, and banking apps, support MFA. To activate it, navigate to the security settings of an account and look for the multi-factor authentication or two-step verification option. Follow the on-screen instructions to enable MFA and select the preferred authentication method.
Set up an authentication app:
Using an authentication app such as Google Authenticator, Microsoft Authenticator, or Authy improves security compared to SMS-based verification. After installing the app on a mobile device, scan the QR code provided by the account’s MFA settings. The app will generate a unique code that refreshes periodically, which must be entered alongside the password during login.
Secure backup codes:
Many services provide backup codes during MFA setup. These codes act as an alternative authentication method if access to the primary MFA device is lost. Store them in a secure location, such as a password manager or offline document, to prevent being locked out of accounts.
Test and verify MFA setup:
After enabling MFA, test the login process to ensure it works correctly. Log out of the account and attempt to sign in again using the new authentication method. If any issues arise, revisit the settings to adjust configurations or update authentication preferences.
