As a tech savvy, I most times get questions relating to OTP from people around me either when they are filling a form online, signingup, login or do payment related transactions online.
In this post I will simply tell you the meaning and the uses.
OTP: What is the meaning of OTP?
OTP simply means One Time Password. And its used to reduce compromising of the normal reuseable password in a secured platform like online payment etc.
If one one gets your One-Time Password now and attempt reusing it another time it won’t work because it expires once its used ones and that feature made it a saver version of reuseable password.
It is the basic technology behind “Token Device” used by banks for internet banking and online payment security.
NOTE: Out side the above context it could also mean On the phone, One True Pairing and so on.
