Summary
One-Time Passwords (OTPs, temporary codes used in two-factor authentication to verify your identity) like HOTP and TOTP have vulnerabilities that let attackers bypass security if they steal the secret key stored on a device or server. This paper proposes HP-OTP, a new OTP scheme that combines your password with the device's unique identifier to make it harder for attackers to forge codes even if they compromise either the device or server.
