  description

  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/import a shared session, or export/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/import shared sessions
  • Export and import session files
  • Login transfer mode for auth-related cookies and keys
  • Optional stricter cookie filtering
  • Clean, simple, privacy-friendly interface
  • Encrypted session handling on your device
  
  Use cases:
  • Developers moving sessions between browsers or environments
  • QA/testing workflows
  • Support/debugging workflows
  • Personal session backup and transfer
  • Secure handoff without sharing passwords
  
  Important security note:
  Treat copied, exported, or shared session data like a password. Anyone with access to a valid session may be able to access the related website account until that session expires, is revoked, or the user logs out.
  
  Session Copy is built for users who want a fast, transparent, and privacy-conscious way to transfer sessions without exposing login credentials.
