OTP stands for One-Time Password.
As the name suggests, it's a password that is valid for only one login session or transaction. Think of it as a secret code that you receive, usually via text message or email, that grants you access to your online accounts or authorizes a transaction. Once you use it, poof! It disappears into the digital ether, never to be used again.
Using an OTP is easy! Here's a quick rundown of the process:
- Login Attempt: Enter your username and password on a website or app.
- OTP Generation: The system generates a unique OTP and sends it to your registered mobile number or email.
- Enter the OTP: You receive the OTP and enter it into the designated field.
- Access Granted: If the OTP is correct and hasn't expired, you gain access to your account!
It's important to also remember the time factor:
Most OTPs are time-sensitive, meaning they expire after a short period (usually 30 seconds to a few minutes). This adds an extra layer of security, ensuring that even if someone intercepts your OTP, they won't have long to use it.
