Early Access Download
Passary Chrome Extension
The browser extension is available as a direct download while we continue polishing it before any Chrome Web Store release. It already supports popup autofill, save and update prompts, keyboard shortcut fill, and right-click autotype with account selection.
Download
Download the latest packaged extension, extract it locally, and load it as an unpacked extension in Chrome.
Important
- The extension is not yet published in the Chrome Web Store.
- You must keep a Passary vault tab open and unlocked to use autofill.
- The bridge only activates on approved Passary origins such as
https://passary.com. - This is an early-access build, so some sites may still need manual fill.
Security model
- The extension does not unlock or decrypt your vault on its own. An unlocked Passary tab remains the only decrypted source of truth.
- The app-side bridge only runs on approved Passary origins such as
https://passary.com,https://www.passary.com, and local development. - Match lookup returns masked summaries only. Plaintext username, password, or TOTP data is requested only for the exact credential and fields you explicitly choose to fill.
- The extension does not keep a decrypted vault copy and does not store plaintext credentials in extension storage.
- Submitted-login captures used for save and update prompts stay only in short-lived in-memory state and expire automatically.
How to install it in Chrome
- Download
passary-extension-chrome.zip. - Extract the archive somewhere you can keep locally, such as your Desktop or a dedicated development folder.
- Open Chrome and go to
chrome://extensions. - Enable Developer mode in the top-right corner.
- Click Load unpacked.
- Select the extracted
passary-extensionfolder from the zip. - Pin the Passary extension in Chrome if you want faster access from the toolbar.
How to connect it to Passary
1. Open and unlock Passary
Open Passary in a normal browser tab and unlock your vault. Keep that tab open. The extension uses that unlocked session as the only decrypted source of truth.
2. Open a login page
Visit a site where you have saved credentials. The extension will look up matching entries based on the current site hostname.
How to use it
Popup autofill
- Click the Passary extension icon.
- Confirm the popup says Vault connected.
- Choose one of the matching accounts to fill username, password, and TOTP if available.
Keyboard shortcut
Use the built-in quick-fill shortcut to fill the best current match:
- Mac:
Command+Shift+P - Windows / Linux:
Alt+Shift+P
Right-click autotype
- Right-click inside a username, password, or OTP field.
- Open Passary in the browser context menu.
- Choose Autotype all, Autotype username, Autotype password, or Autotype TOTP.
- If the site has multiple saved accounts, choose the specific account you want.
Save and update prompts
- Submit a login on a supported site.
- Open the Passary popup after submission.
- Passary can offer to save a new login or update an existing one based on the submitted credentials.
Current extension limitations
- You must keep an unlocked Passary vault tab open while using the extension.
- The extension is not yet store-published, so updates are manual for now.
- Some sites with unusual forms or aggressive frontend frameworks may still need manual fill or popup-based selection.
- The extension never auto-submits forms.
- This extension does not yet cover passkeys.
- The extension intentionally will not connect to non-Passary origins, even if they host a copied build of the app.
Troubleshooting
- If the popup says Passary is not connected, go back to your Passary vault tab and confirm it is still open and unlocked.
- If the extension does not update after a change, reload it in
chrome://extensions. - If a site does not fill correctly, try the popup chooser instead of quick fill.
- If you change devices or clear browser state, you still need your vault backup and keyfile backup just like the main app.
