WebMay 10, 2012 · There are two different algorithms to choose from for your OTP generators. Time Based (TOTP) and Counter Based (HOTP). For TOTP, your token generator will hash the current time and a shared secret. The server validates the OTP by comparing the all hashes within a certain window of time to the submitted value. WebOTP window: The size of OTP window defines number of valid OTP for authentication. When the counters are out of sync, this parameter determines the difference between the counter on the token and the server. Based on the difference, the server can recalculate the next OTP value to validate with the OTP received from the token.
