WebOne-time password (OTP) systems provide a mechanism for logging on to a network or service using a unique password that can only be used once, as the name suggests. The static password is the most common authentication method and the least secure. If "qwerty" is always your password, it's time to change. WebOTP generation algorithms typically make use of pseudorandomness or randomness to generate a shared key or seed, and cryptographic hash functions, which can be used to …
