What is OTP (One-Time Password)?

An OTP (One-Time Password) is a unique, temporary code used to authenticate a user or verify a transaction. OTPs are valid for a short period or for a single use, making them a secure method to prevent unauthorized access.

Key Features:
-Temporary & Unique: Each OTP is valid only once and expires quickly.
-Enhanced Security: Reduces the risk of fraud and unauthorized access.
-Delivery Channels: Sent via SMS, email, voice call, or authenticator apps.
-Use Cases: Account login, password reset, banking transactions, and online purchases.

Difference from Regular Passwords:
OTP: Temporary, single-use, dynamic.
Regular Password: Permanent, reusable, and static until changed.

Example:
When logging into a banking app, you may receive an OTP like “492831” via SMS, which you must enter to complete the login or confirm a transaction.
