OTP means “one-time password.” It is a code that is used only once, usually to verify your identity when you log in, make a payment, or confirm an action online.
People often receive an OTP by SMS, email, or an app. For example, when you sign in to a website or approve a transaction, you may need to enter the OTP before you can continue. It adds an extra layer of security.
Meaning & Usage
An OTP is a temporary security code. It works for a short time and then expires, so it cannot be reused. This helps protect accounts and personal information.
Examples
You may see OTPs when you are logging into your bank account, resetting a password, or confirming a new device. The code is usually short and easy to enter.
Why do websites use OTP?
Websites use OTPs to make accounts safer. Even if someone knows your password, they usually still need the OTP to get in.
How do I get an OTP?
You usually get it by text message, email, or through an authentication app after you request it.
Can an OTP be used again?
No. An OTP is meant to be used only once and then it expires.
