What is Multi-factor authentication?
Multi-factor authentication (MFA) is a security system that requires you to provide more than just a password to log in to an account. It adds an extra layer of protection by making it more difficult for unauthorized users to access your information, even if they steal your password.
- How it works:
• Enter your username and password as the first factor.
• Then, user will be prompted 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
MFA significantly reduces the risk of unauthorized access because even if someone steals your password, they wouldn't be able to log in without your phone or another authentication factor.
- 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 a fingerprint scan
• Reduced Password Risk: Passwords are often weak or reused, making them vulnerable to phishing attacks or breaches. MFA makes stealing passwords much less effective.
• Improved Compliance: Many regulations in different organizations require strong authentication for access to sensitive data. MFA can help organizations meet these compliance requirements.
• Scalability: MFA can be easily implemented for all users in an organization, from employees to students
• Convenience: MFA can be surprisingly convenient. Many methods, like fingerprint scanners or verification codes on your phone, are quick and easy to use.
Overall, MFA is a powerful tool for enhancing online security for both individuals and organizations. Passwords are a common security measure, but they're not foolproof. There are two main categories of risk: weak passwords themselves (vulnerabilities), and ways attackers can steal them (threats).
