Chapter 1
Two-factor authentication (2FA) provides an extra layer of security to protect your accounts. By requiring not only something you know (like a password) but also something you have (like a code from your phone), it dramatically reduces the risk of unauthorized access.
Implementing 2FA via email or SMS messages OTP is a win-win solution for both businesses and users. It significantly enhances security, improves user trust, and helps businesses meet compliance regulations - all without adding major complexity. However, businesses should always encourage users to choose OTP + strong passwords rather than relying on just OTP alone for maximum protection.
