One Time Password
A One-Time Password (OTP) is a secure, temporary code that is valid for only one login session or transaction. OTPs are widely used in various sectors, including banking, e-commerce, and online services, as an added layer of security. Unlike traditional passwords, which remain the same until changed by the user, OTPs are generated dynamically and expire after a short period, making them much harder for hackers to intercept and use maliciously.
How OTP – One-Time Password Works
OTPs can be delivered through several channels:
- SMS: The most common method, where the OTP is sent to the user’s registered mobile number.
- Email: The OTP is sent to the user’s registered email address.
- Authenticator Apps: These apps generate OTPs on the user’s device without needing a network connection.
- Hardware Tokens: A physical device generates the OTP.[1]
