One-Time Password (OTP)
Definition - What does One-Time Password (OTP) mean?
A one-time password (OTP) is type of password that is valid for only one use.

Techopedia explains One-Time Password (OTP)
It provides more enhanced protection than static passwords, which remain the same for multiple login sessions. OTP works through randomness algorithms that generate a new and random password each time they are used.
The algorithm always uses random characters and symbols to create a password so that a hacker/cracker cannot guess the future password. A OTP uses several techniques to create a password, including:
- Time-Synchronization: The password is valid for only a short period of time.
- Mathematical Algorithm: The password is generated using random numbers processed within an algorithm.
