One-Time Password (OTP)

A one-time password (OTP) is a unique authentication code commonly used to access specific networks or services via mobile devices. OTPs are typically time-sensitive and expire after a short duration, usually around 30 seconds. They are often generated and used through mobile authentication applications like Google Authenticator, Okta Verify, or Authy. OTPs provide an extra layer of security compared to traditional passwords and are commonly used as a supplement to enhance overall security.
