SenKey

Store and autofill passwords from your own backend with Google sign-in and client-side encryption.

SenKey is a self-hosted password storage and autofill extension for Chrome and other Chromium-based browsers. Instead of locking your credentials into a third-party password manager service, SenKey lets you keep control of your own backend while still giving you a fast, practical browser autofill experience. SenKey is built for people and teams who want: - their own server or cloud backend - Google account based user separation - client-side password encryption before upload - saved login URLs for reopening the correct sign-in page later - a lightweight, focused password fill workflow How SenKey works: 1. You sign in to the extension with Google. 2. You connect the extension to your own SenKey backend with an API URL and API key. 3. When you save a credential, SenKey encrypts the password in the browser before it is uploaded. 4. SenKey stores credentials per signed-in Google user on your backend. 5. When you click a saved credential, SenKey can fill the current login page or navigate to the saved login page and autofill there. Key features: - Self-hosted credential storage Use your own backend instead of relying on a hosted password vault service. - Client-side password encryption Passwords are encrypted in the extension before they are sent to the server. - Google sign-in SenKey uses Google sign-in to separate data by user. - Login URL memory SenKey can save the full login page URL, not just a domain, so it can reopen the correct sign-in page later. - Navigation plus autofill If you are not already on the right login page, SenKey can open the saved login page and autofill after navigation. - Support for modern login flows SenKey includes logic for many standard, SPA, shadow DOM, and multi-step login forms. - Credential editing Update usernames, passwords, domains, and saved login URLs directly from the popup. - Built-in help The extension includes a built-in help page for setup and daily use. Who SenKey is for: - developers who want to host their own password backend - small teams who want a lightweight private credential workflow - users who prefer a simple extension backed by infrastructure they control Important note: SenKey is not a zero-setup consumer password manager. It requires you to connect the extension to your own backend or a backend deployed for you. If you want complete control over where your credential data lives, that is the point. Typical setup: - deploy the SenKey backend to your own PHP host or Google Cloud Run - sign in with Google inside the extension - paste the backend API URL and API key into SenKey settings - save credentials and use the `Fill` tab to autofill them later SenKey is designed to stay focused: - save credentials - reopen the correct login page - autofill reliably - keep your backend under your control
