An idempotency key is a unique identifier generated by the client (usually a UUID), which the server uses for deduplication: on first receipt it executes and caches the result, and when the same key arrives again it directly returns the cached result.

UnverifiedIdempotency keys are a common means in distributed systems of preventing the same operation from being executed multiple times: the caller carries a globally unique identifier when initiating a request, the server deduplicates on that identifier, and on encountering a duplicate request with the same key it directly returns the first result without re-executing the side effects.69% similarUnverifiedAn account session credential (Token) is an encrypted string issued by the server to the browser after a user successfully logs in, used to prove that the visitor has passed identity verification.64% similarUnverifiedA token is the core carrier of login authentication; after a successful login, the back end generates a random string and returns it to the front end, which saves it in localStorage and includes the token with every request for back-end verification.63% similarUnverifiedUnlike TOTP-based two-factor authentication, Passkeys use a challenge-response mechanism in which the service provider sends a random challenge value at each login, which the device signs with the private key and returns, eliminating the one-time password that could be intercepted and replayed by a man-in-the-middle.61% similarUnverifiedA secrets proxy is an intermediary layer between an application and real credentials, letting the application touch only placeholders and substituting the real values only when requests are sent to authorized hosts.60% similar
