Session Copy

Copy and restore encrypted login sessions for any website. Offline, private, and built for secure transfer between browsers.

Session Copy is an open-source browser extension that helps you copy, export, and import website sessions securely. It lets you transfer an authenticated session without sharing the actual username or password. You can copy a session, paste or import a shared session, or export and import it using a file-based workflow. Because Session Copy handles sensitive session data, transparency matters. The extension is open source, so developers and security-conscious users can inspect how it works. Key features • Open-source and transparent • Copy sessions with one click • Paste and import shared sessions • Export and import encrypted session files • Captures localStorage, sessionStorage, and cookies (including HttpOnly) for the active site • Login transfer mode — copies auth-related cookies and keys by default • Optional stricter cookie filtering when full sync is enabled • Clear site data — reset cookies and storage for the active tab if a paste or restore goes wrong • Light and dark themes — follows your system by default; choose System, Light, or Dark in Settings • Encrypted on your device before anything is copied or saved • Clean, simple, privacy-friendly interface Use cases • Developers moving sessions between browsers or environments • QA and testing workflows • Support and debugging workflows • Personal session backup and transfer • Secure handoff without sharing passwords Important security notes • Treat copied, exported, or shared session data like a password. Anyone with access to a valid session may be able to use the related website account until that session expires, is revoked, or the user logs out. • Clear site data only affects the site on your active tab and signs you out of that site. It cannot be undone. Session Copy is built for users who want a fast, transparent, and privacy-conscious way to transfer sessions without exposing login credentials.
