Bearer Token Copier by Pavel Poddubny is a Chrome extension that extracts Bearer tokens from Authorization headers for developers and testers. It detects 'Authorization: Bearer' headers in outgoing requests and presents the most recent token with a one-click copy action, keyboard shortcut support, and visual confirmation. The extension requires no configuration and keeps a minimal interface. It targets API testers, QA engineers, and security professionals who need fast token transfer into tools like Postman or cURL.

What is Bearer Token Copier used for?

The extension targets a single, practical need: automatically locating and exposing Bearer tokens embedded in Authorization headers so users do not inspect the Network tab manually. It monitors XHR and Fetch requests in real time, highlights the most recent authentication string, and presents a direct way to place that token on the clipboard, reducing manual copying during API testing and debugging.

How does it behave under normal browser load?

It is designed to stay lightweight and unobtrusive: the tool keeps a minimalist user interface that remains inactive until needed and is described as having a minimal impact on browser performance. Real-time monitoring is limited to outgoing requests, which preserves responsiveness compared with full developer suites that inspect every detail of page activity.

Does the extension keep or transmit captured tokens?

Privacy is handled locally by design: the extension operates inside the browser and does not store or log sensitive authentication data externally, according to its design notes. That means captured tokens are intended only for immediate transfer to the clipboard, not for later retrieval from an internal history or external server.

How well does it integrate with API workflows and Chromium browsers?

It complements existing API clients and works across Chromium browsers: the extension is useful when pasting tokens into Postman, Insomnia, or cURL, and supports keyboard shortcuts to accelerate that transfer. It is available for Google Chrome and other Chromium-based browsers, and it is specifically optimized for the standard 'Bearer' scheme in Authorization headers sent by XHR or Fetch.

A focused utility best paired with an API client

This extension suits developers and security testers who prefer compact, single-purpose tools rather than a full developer suite; it is a practical adjunct for moving tokens into API clients. Users who need historical token logs or multi-scheme detection should use broader tooling alongside it. Tip: use it together with your chosen API client to capture and immediately record tokens in reproducible requests.
