token-grab

Copy the bearer token your browser is already sending.

A tiny Chrome/Edge extension for developers that captures auth headers — Authorization: Bearer, X-Api-Key and more — and copies the token in one click for API clients, curl or test scripts. Values are masked, auto-expire, and never leave your machine.
