Passthrough
The passthrough bridge

Get past the login wallswithout ever seeing the form.

Bureaucratic files live behind MFA, captchas, and institutional logins that block any outside agent. The Passthrough extension solves this the only honest way: you log in as yourself, then hand the page to us with one click. We scrape the forms, fill them from your vault on our server, and route the completed files onward — to your inbox and back into your Documents. The form never appears on your screen.

How it works

You log in — as yourself
Open the institution's portal and clear MFA / captcha the normal way. Your credentials never leave your browser.
One click to hand off
Open the Passthrough popup and press Scrape. It collects every PDF and form on the page using your authenticated session.
Filled on our server
The files are sent to Passthrough, matched against your saved dataset, and filled in the background. You never see the form.
Emailed & archived
Completed files are (optionally) forwarded to an email of your choice and dropped into your Documents, sorted and receipted.

Install in 4 steps

  1. 1
    Unzip the downloaded passthrough-extension.zip file.
  2. 2
    Open chrome://extensions in Chrome (or any Chromium browser).
  3. 3
    Enable Developer mode (toggle in the top-right).
  4. 4
    Click Load unpacked and select the unzipped folder.

First run

Pin the Passthrough icon in your toolbar. Open its popup and paste your backend endpoint — your app's public intake URL. Optionally add a forwarding email and your JSON dataset (or leave it blank to use the vault on file).
Navigate to the portal, log in, land on the page with the forms, and press Scrape & auto-fill this page. The extension quietly downloads every PDF / DOCX / XFDL it finds using your session cookies, ships them to Passthrough, and closes.
Filled files show up under Documents here — sorted, receipted, and ready. No form ever appears on your screen.

Passthrough never stores your portal credentials. The extension only runs on the tab you point it at, only when you click it.
