140 Define OTP lifespan


Summary

One-time passwords (OTP) must have a maximum lifespan of 60 seconds.


Description

OTPs are tokens that help hinder phishing (impersonation) attacks. They should be generated using secure cryptographic algorithms, be sent over a protected channel and have a short lifespan that considers network delay and entry time. Furthermore, it should only be possible to use them once within their validity period.
