Account Manager

About

Account Manager lets you treat website logins as savable, switchable, and shareable profiles.

What you can do:

Save the cookies and localStorage of any website you are logged into as a named profile.

Switch between multiple accounts on the same site with one click, without repeating the log-out and log-in cycle.

Keep profiles only on your device as local profiles, or sync them to your cloud account so the same profile is available from other browsers you control.

Attach a per-profile HTTP, HTTPS, or SOCKS5 proxy so each saved account can use its own configured network route.

Run liveness probes against profiles and see which saved sessions are still valid.

Share a cloud profile with another Account Manager user you trust. Owners can attach access rules, such as allowed time windows or blocked IP ranges, that are enforced locally in the recipient's browser.

Privacy-first design:

The extension carries no analytics, advertising, or telemetry.

Cookies, localStorage, and proxy passwords are encrypted with AES-256-GCM at rest on the server. Sensitive session payloads are returned through a second AES-256-GCM encrypted transport envelope for client-side decryption by the extension.

You can use the extension entirely offline by keeping profiles local in chrome.storage.local. No account or backend connection is required for local profiles.
