MOTP/HOTP/TOTP AuthAuthentication and authorization

Overview

Client wanted to protect a web based CMS with a OTP. We built all three OTPs.  The first one was an Event-based OTP which uses HMAC One Time Password. This is the HOTP. 

The second one, TOTP built, was Time based OTP where the changing factor is time instead of the counter. The time increment was set to 45 seconds.

The third was the Mobile OTP, MOTP which is an authentication protocol.
