Time-Based One-Time Password (TOTP)
A temporary passcode that changes based on time for authentication.
Understanding Time-Based One-Time Password (TOTP)
Time-Based One-Time Password (TOTP) is a secure authentication mechanism that generates temporary passcodes based on the current time. It is widely used in two-factor authentication (2FA) systems to enhance security by requiring a dynamically changing code in addition to a password.
TOTP vs. Other Authentication Methods
Compared to SMS-Based OTPs
More secure as it does not rely on network-based delivery (reducing SIM-swapping attacks).
Faster and works offline.
Compared to Static Passwords
Eliminates the risk of password reuse and brute-force attacks.
Compared to Hardware Tokens
More cost-effective as it can be implemented via smartphone apps instead of dedicated devices.
Future Trends in TOTP Security
Biometric-Integrated Authentication – Combining TOTP with facial or fingerprint recognition.
AI-Driven Authentication – Using behavioral analysis to detect suspicious authentication attempts.
Decentralized Authentication – Enhancing security using blockchain-based authentication methods.
