What Is UUID Access Token?

An access token is presented on each request. As an opaque UUID it is validated against a grants table with an expiry.
Keep lifetimes short (minutes) and issue a separate refresh token for obtaining new access tokens.

How to generate

Mint a v4 UUID on successful auth.
Record it with an expiry in your store.
Reject after expiry; issue via refresh token.

Use Cases

Bearer tokens for REST APIs.
WebSocket connection auth handshakes.
Microservice hop credentials.

Code Examples

JavaScript

const id = crypto.randomUUID();

Python

import uuid
id = uuid.uuid4()

Frequently Asked Questions

UUID access token vs JWT?

A UUID is an opaque reference validated server-side; a JWT is self-contained and signed. UUIDs are simpler to revoke, JWTs avoid a lookup.

How long should it live?

Minutes, not hours. Short lifetime bounds the blast radius if leaked.
