Access Token

Session Management

Bearer credential used to authorize API requests; should be short-lived and scoped.

Definition

An access token is a credential (often a signed JWT or opaque string) presented to APIs to authorize requests. Good practice uses short lifetimes, narrow scopes, and secure storage.

In plain English Bearer credential used to authorize API requests; should be short-lived and scoped.

Why this matters

Why it matters: Token theft enables impersonation; limiting scope and lifetime reduces blast radius.

Example

Example: Issue an access token valid for 15 minutes with scope “read:profile”, and rotate it via a refresh token.
