There are different types of OTP generators: Concrete OTP algorithms vary significantly in their details. It is necessary because otherwise, it would be easy to predict future OTPs by observing previous ones. OTP generation algorithms typically make use of pseudorandomness or randomness. Some OTP systems also aim to ensure that a session cannot easily be intercepted or impersonated without knowing unpredictable data created during the previous session, thus reducing the attack surface further. It means that a hacker who manages to record an OTP that was already exposed to log into a service or to enforce a transaction will not be able to use it since it will no longer be active. The most crucial advantage addressed by dynamic one-time-passwords is that, in contrast to traditional passwords, they are not vulnerable to replay attacks.
What are the benefits of using an OTP generator?

They ensure that the one-time password requires access to something a person has (such as a Hideez Key with a built-in OTP generator built, or a cellphone) as well as something a person knows (such as a PIN). Some implementations of OTP generators also incorporate two-factor authentication. In simple terms, a service accepting OTPs requires a user to select a preferred OTP generator to deliver this dynamic password. The use of OTP helps to avoid many disadvantages that are associated with traditional (static) password-based authentication. OTP is a password that is valid for only one login session or transaction on a computer system or other digital device.
What does OTP Mean, And How does it work? Hideez created a reliable and tamper-resistant way to do this with multifunctional hardware security keys that can generate OTPs, store & autofill your passwords, and more. When dealing with high-load web applications like mail services, banking, or even Amazon and Facebook, using an OTP authentication (one-time-password authentication) means a way to avoid keylogging attacks.
Even when the user adheres to the recommendations of password length and complexity, in some cases, it is not enough to avoid password theft.
