Validates a hash-based one-time password.

Syntax

otpserver.isHOTPPasswordValid(keySecret_Buffer, passwordLength, counter, password, [callback])

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for this method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

Use this method to validate a hash-based one-time password (HOTP) by using explicit HOTP parameters. For this method to work, no user details need to be provided in Users collection.
