HOTP vs TOTP
Developers should learn HOTP when implementing or integrating authentication systems that require robust security against replay attacks, such as in banking apps, VPN access, or enterprise software meets developers should learn totp to implement secure authentication systems in applications, especially for user login flows in web and mobile apps where enhanced security is required. Here's our take.
HOTP
Developers should learn HOTP when implementing or integrating authentication systems that require robust security against replay attacks, such as in banking apps, VPN access, or enterprise software
HOTP
Nice PickDevelopers should learn HOTP when implementing or integrating authentication systems that require robust security against replay attacks, such as in banking apps, VPN access, or enterprise software
Pros
- +It is particularly useful in scenarios where network connectivity is unreliable, as HOTP codes do not rely on time synchronization like TOTP, making it suitable for offline or low-latency environments
- +Related to: two-factor-authentication, cryptography
Cons
- -Specific tradeoffs depend on your use case
TOTP
Developers should learn TOTP to implement secure authentication systems in applications, especially for user login flows in web and mobile apps where enhanced security is required
Pros
- +It is widely used in scenarios like banking, email services, and enterprise software to protect against credential theft and phishing attacks, as it requires both something you know (password) and something you have (a device generating the TOTP)
- +Related to: two-factor-authentication, oauth
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use HOTP if: You want it is particularly useful in scenarios where network connectivity is unreliable, as hotp codes do not rely on time synchronization like totp, making it suitable for offline or low-latency environments and can live with specific tradeoffs depend on your use case.
Use TOTP if: You prioritize it is widely used in scenarios like banking, email services, and enterprise software to protect against credential theft and phishing attacks, as it requires both something you know (password) and something you have (a device generating the totp) over what HOTP offers.
