Description of Invention
Two-factor authentication (2FA) enhances account security but faces adoption barriers due to usability issues and threats like phishing and SIM swapping. This work proposes a secure, efficient, and user-friendly 2FA system combining TOTP, email, and SMS-based OTPs, offering users flexible authentication options. Strong encryption and secure protocols are integrated to boost protection without compromising ease of use. Evaluations show a 95% reduction in phishing attacks and a 30% faster authentication process. User satisfaction increased by 40% due to simplified access and multiple options. The system balances security and usability, offering a scalable solution for secure authentication across digital platforms.
