OTP, What is OTP and what does it mean? All the things will be discussed here. So guys are you ready for the things.

‘O’-One

‘T’-Time

‘P’-Password

Well OTP is in fact an acronym that is used for One time Password. Let me here discuss with all of you about the topic that is OTP in detail.

What is OTP?

As now you know that OTP is the acronym that stands for One Time Password, it is very help and having a very great significance. Let me discuss all the things with the help of the following listed points.

1. An OTP that is in fact a password.
2. This password is in fact is valid for only one login session or you can say also transaction.
3. These things are performed and being done on a computer system or other digital device.
4. One of the important thing about One Time Password is that this very OTP prohibits a number of drawbacks.
5. Let me mention all the drawbacks as under-

• This include shortcomings and these are the shortcomings which are associated with traditional password-based authentication.
• There are quite a few number of implementations that incorporate two factor authentication.
• And thus there is a certainty that the one-time password requires access to somethings that one is having and also there is something that a person is having. May be this will be in the form of pin.

Thus dear these are some of the things about the OTP that is One Time Password in this section. Let me move on the another section where I will mention some important things about the One Time Password.

Some Important Things About OTP

From the very name OTP i.e One Time Password you all will be aware very well about the things. Also many of you are experienced about the case. Nowadays the world is going across a change of digital revolution. Most of the people among you may have some of the idea about the OTP and what actually the term is and what are the things inside this. Apart from this, many people who are using online transaction will surely have the idea as there in the situation of transaction OTP is needed.

Here I am going to mention some important points about the One Time Password. So guys and girls just go through the things that are mentioned below-

1. The most important benefits an OTP is addressing is that, in contrast to static password, they are not vulnerable to replay attacks.This is one of the advantageous feature of an one time password.

• The above mentioned point refers that if there is a potential intruder who manages to record an OTP that was already used to log into a service or in order to conduct a transaction will not be able to abuse it. This is because of the reason that OTP will no longer be valid.

Advantages of OTP

Well there are quite a few advantages of One Time Password. In this section I am going to mention some of the beneficial points about the OTP. As in the previous section I have discussed about the case that there is very less chance or it will be correct say negligible chance for any kind of replay attack.

Apart from the above mentioned  advantageous features of an OTP that is One Time Password there are also quite a few another benefits as well. Let me mention one another second major advantage.

The second Benefit here is that any user who in fact uses the same password that he or she gets for transaction for multiple systems, is not made vulnerable on all of them. Thus this is one of the beneficial point in the case and the situation if the password for one of these is gained by an attacker.

Thus there are a lot of mechanism available that ensures the users that their transactions are safe and there will be no any attack or ant type of security lacks.  Well one of the thing here is that a number of OTP systems is there also which actually  aim to ensure that a session cannot easily be intercepted or impersonated without knowledge of unpredictable data that is created during the last session. This in fact helps in minimizing any chance of attack further.

Thus dear readers these are some of the points regarding the advantage of One Time Password. Now let me move on the another section. So guys if you are interested to know more about One Time Password then go further.

The Way of Generating OTP

Well in the earlier section you came to know about the advantages of one time password. Also you get to know what actually the term One Time Password refers to and what are the things inside the topic. Here I am going to share about the way of generating OTP. How in fact an one time is generated? This will be discussed in this section.

So guys and girls let me here disscuss about the algorithm of OTP. In fact One Time Password generation algorithms typically make use of randomness as well as pseudorandomness. Thus dear this very thing makes prediction of successor OTPs by an attacker difficult and that of hash function as well. This can be used to get a value. But these are hard to reverse and therefore there will be difficult for an attacker to get the data that was used for the hash. This is important because otherwise it would be easy as well as simpler to predict future OTPs by observing previous ones. In this very way none can get prediction about the OTP, hence enhancing the security for One Time Password.

There are quite a few different ways as well. In fact different ways to make one aware about the next OTP. Many systems use different mechanism. In fact some systems use tokens. User carries the token. This generate OTPs.

Also many of systems are having software. The software actually runs on the phone of User.
