Chrome extension · Manifest V3

Bulk Login Tab Opener

Point it at a spreadsheet of URL / username / password rows. It opens one tab per row and fills the login form on each — with or without pressing sign in for you.

Spreadsheet format

Column 1URLhttps:// is added automatically if missing.
Column 2UsernameEmail, username or account ID.
Column 3PasswordUsed in memory only, never stored.

The first sheet is used. A header row is detected and skipped automatically, and rows without a usable URL are reported instead of opened.

Install

  1. 1Unzip the downloaded file.
  2. 2Open chrome://extensions in Chrome, Edge, Brave, Arc or Opera.
  3. 3Enable Developer mode with the toggle in the top-right corner.
  4. 4Click Load unpacked and select the unzipped folder.

Then click the extension icon, choose your file, pick Auto-fill and submit or Auto-fill only for the run, and open all tabs.

Handling of credentials

Your file is parsed inside the extension popup. Credentials are held in memory for the duration of the run only — nothing is written to browser storage, disk or any server, and no network request leaves your machine. Re-select the file for each run.

Sites protected by CAPTCHA, SSO redirects or MFA can't be completed automatically; those tabs still open with whatever fields could be filled, and the popup flags them.
