Cookie King

Cookie King securely moves authorized website sessions between your devices. Use it when you need to continue a signed-in website on a new computer, another browser, or a temporary environment without repeating every sign-in step. Cookie King encrypts the session snapshot in your browser, uploads only ciphertext to the compatible Worker you configure, and restores it when you paste the share code on the destination device. Key features: - One-click push and one-click session restore - Choose Cookie only or Cookie + Storage for each website - Handles related sign-in pages and returns to the page where you started - Keeps one local login record and last-login time per website - Optional per-site automatic push and pull - Local, operation-scoped restore diagnostics with exact write results Privacy and security: - New ck4 snapshots use a separate client-side encryption key - The decryption key is not sent to the Worker - The Worker stores encrypted snapshots, not plaintext Cookie or Storage values - Restore diagnostics stay on the local device - Diagnostics do not store Cookie names, Cookie values, share codes, or full request URLs - Site icons come from Chrome's local favicon database, not a third-party icon service Requirements: - Configure your own compatible Cloudflare Worker before using push or restore - Use Cookie King only with accounts, websites, and devices you are authorized to access Some websites bind sessions to a device, network, or additional verification step. Those websites may still require an official sign-in. ```
