One-Time Password (OTP)
One-Time Password (OTP) is an authentication method that generates unique, temporary codes valid for a short period. Used primarily in Two-Factor Authentication (2FA), OTP enhances security by preventing credential reuse and replay attacks. It can be delivered via authenticator apps, SMS, or email and supports TOTP (time-based) and HOTP (counter-based) algorithms. Keycloak enables OTP customization, including hash algorithms, token length, and expiration time. While OTP improves security, risks like SIM swapping and phishing highlight the need for safer alternatives such as WebAuthn or passkeys.
