SenKey

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

SenKey is a self-hosted password autofill extension that puts you in complete control of your credentials. Instead of trusting a third-party password manager with your logins, SenKey stores your credentials on a server you own and operate — whether that's a personal web host or a Google Cloud Run instance. How it works Sign in with your Google account, point the extension at your server, and SenKey securely fetches your saved credentials on demand. When you land on a login page, SenKey detects the matching credential and fills your username and password with a single click — no typing, no copy-pasting. Multi-user support Each Google account gets its own isolated credential vault on your server. Share your server with family, a small team, or trusted friends — everyone signs in with their own Google account and sees only their own passwords. No shared secrets, no mixed-up credentials. You own your data Your passwords never leave your infrastructure. SenKey works with a lightweight PHP backend you deploy yourself in minutes — either uploaded to any standard web host, or deployed to Google Cloud Run with a single command. There are no subscriptions, no cloud accounts to create, and no company holding your data. Key features Sign in with Google — no separate account or master password to remember One-click autofill on any login form, including React and Vue single-page apps Add, view, and delete credentials directly from the extension popup Automatically highlights credentials that match the current site Works with any HTTPS web host or Google Cloud Run Open source — inspect every line of code yourself Who it's for SenKey is built for developers, privacy-conscious users, and small teams who want the convenience of a password manager without handing their credentials to a third party. If you already run a web server or are comfortable with a one-command cloud deploy, setup takes under ten minutes.
