One-Time Password (OTP)

    A one-time password (OTP) is a unique authentication code that is typically used to access a network or service via a mobile device. OTPs are typically time-limited, lasting only until the next code is generated (usually every 30 seconds). OTPs are frequently used in conjunction with a mobile authentication app such as Google Authenticator, Okta Verify, or Authy. OTPs are more secure than passwords and are usually used in conjunction with them as a security measure.
