one-time password
Single-use security code
A one-time password is a security code valid for only a single login session or transaction.
Unlike permanent passwords, these codes expire after use or within a short time window, typically arriving via text message, email, or authenticator app: Enter the one-time password we sent to your phone.
Often abbreviated OTP.
