What is multi-factor authentication?
Multi-factor authentication (MFA), also sometimes called two-factor authentication (2FA) for systems with two factors, is an extra layer of security for your online accounts. It adds an additional step to the login process beyond just your username and password.
- How it works
• You enter your username and password as usual.
• The system then prompts you for a second factor, such as:
1. A code sent to your phone via text message (SMS) or generated by an app on your phone
2. A fingerprint scan
3. A security question answer
Since attackers are unlikely to have both your password and your phone (or other second factor), MFA makes it much more difficult for them to break into your accounts.
MFA is a highly recommended security practice for all your important online accounts, such as email, bank accounts, social media, and any other accounts that contain sensitive information.
- Key benefits of using MFA
• Stronger Security: MFA adds an extra layer of defence against unauthorized access. Even if a hacker steals your password, they won't be able to log in without the additional verification factor, like a code from your phone or fingerprint scan.
• Reduced Password Risk: Many cyberattacks rely on stolen, weak or reused passwords making them vulnerable to phishing attacks or breaches. MFA makes stealing passwords much less effective
• Protects Sensitive Data: MFA is especially important for safeguarding sensitive data, such as financial accounts, medical records, or confidential business information.
• Convenience: MFA can be surprisingly convenient. Many methods, like fingerprint scanners or verification codes on your phone, are quick and easy to use.
