OTP (One Time Password) :-

OTP (One Time Password) एक ऐसा temporary password/code होता है, जो किसी Login Session, Account Verification या Transaction को authenticate/verify करने के लिए उपयोग किया जाता है। इसे One-Time Password या Dynamic Password भी कहा जाता है।

OTP सामान्यतः एक specific verification attempt के लिए valid होता है और इसकी validity एक limited time period तक रहती है। Validity समाप्त होने के बाद OTP Expire हो जाता है और उसका दोबारा उपयोग नहीं किया जा सकता।

OTP user के Registered Mobile Number, E-mail ID या किसी supported authentication application/service पर भेजा जा सकता है।

Note: OTP की length और validity fixed नहीं होती; यह bank, website या service provider के अनुसार अलग हो सकती है। इसलिए इसे हमेशा 6-digit और 10-minute का universal rule नहीं मानना चाहिए।

English:-

OTP (One Time Password) is a temporary password/code that is used to authenticate or verify a login session, account verification, transaction, or other digital activity. It is also known as a One-Time Password or Dynamic Password.

An OTP is generally valid for one specific verification attempt and remains valid only for a limited period of time. After the validity period expires, the OTP becomes invalid/expired and cannot be used again.

An OTP may be sent to the user's registered mobile number, email ID, or a supported authentication application/service, depending on the system.

Note: The length and validity period of an OTP are not fixed universally. They may vary depending on the bank, website, application, or service provider. Therefore, a 6-digit OTP with a 10-minute validity should not be considered a universal rule.
