Uzero is a free, GPL-3.0 browser extension that puts your signed-in Google accounts in your chosen order. Pin mode opens Google links in the account you pick. Reorder in Google guides you through signing out and back in so Google's /u/0, /u/1 numbers match.

Set up Uzero

Chrome, Edge and Firefox

1. Install Uzero from your browser's extension store when the listing is available. Firefox requires version 140 or later.
2. Sign in to your Google accounts in that browser.
3. Open Uzero from the browser's extensions menu or toolbar.
4. Drag your accounts into your order. You can also focus an account and press Alt + Up or Alt + Down.
5. Turn on Pin. Google links from outside Google open in your first account. You can choose a different account for each Google service in Uzero's settings.

Pin mode does not sign you out or need your passwords.

Safari on Mac

1. Install Uzero from the App Store when the listing is available, then open the Uzero app.
2. In Safari, open Settings > Extensions and turn on Uzero.
3. Allow Uzero access to Google sites. If Safari offers Always Allow on Every Website, you can use that choice. Uzero needs access to Google sites to work.
4. Open a Google page in a regular Safari window and sign in to the accounts you want to use. Keep a Google tab open so Uzero can read the account list.
5. Open Uzero from Safari's toolbar or extensions menu. Put your accounts in order and turn on Pin.

Safari on iPhone and iPad

1. Install Uzero from the App Store when the listing is available, then open the Uzero app.
2. Open Settings > Apps > Safari > Extensions > Uzero and turn on the extension. On some iOS versions, Safari sits directly under Settings.
3. Allow access to Google sites, or choose Always Allow on Every Website when Safari offers it.
4. Open a Google page in a regular Safari tab. Sign in to your Google accounts and keep a Google tab open.
5. In Safari's page menu, open the extensions menu and choose Uzero. Put your accounts in order and turn on Pin.

On iPhone and iPad there are no keyboard shortcuts and no side panel.

Uzero never acts in Safari private windows or tabs.

Make Google's own order match

Save your open work first. Have each account's password, 2-Step Verification method and recovery options ready. A reorder signs you out of every Google account in this browser.

Open Uzero and choose Reorder in Google, then confirm. Follow the guide and sign back in to each account in the order shown. Type passwords only on Google's page. Uzero never reads, fills or stores them.

Questions and fixes

Why aren't my accounts showing?

Check that you signed in to Google in the same browser where you opened Uzero. Open Uzero again after signing in.

On Safari, keep a Google page open in a regular tab. Uzero reads the account list through that tab. Check that Uzero is on in Safari's extension settings and that you allowed access to Google sites. It never acts in private windows.

Why does a link open in the wrong account?

Open Uzero and check the order. Turn on Pin and check whether you chose a different account for that service.

Pin mode handles Google links from outside Google, such as chat apps, bookmarks and the address bar. It leaves Google's own in-app links alone. To switch an open Google tab, use Uzero's tab-switching control.

What's the difference between Pin and Reorder in Google?

Pin changes which account Google links open in. It leaves you signed in and does not change Google's own account numbers.

Reorder in Google signs you out once and guides you back in, one account at a time. Google's sign-in order sets /u/0, /u/1 and the numbers after them.

A reorder got stuck. What should I do?

Check Google's sign-in page for a password prompt or an extra verification step. Complete those on Google's page. Keep the guide open and use the email it shows for the current step.

If the wrong account signed in, choose Try again in the guide. Uzero signs you out and starts over. If you still cannot continue, contact support with the step where it stopped. Never send passwords or verification codes.

My password manager picked the wrong email. How do I fix it?

Clear the email field on Google's page. Use Copy in Uzero's guide and paste the email for that step. If the wrong account already signed in, choose Try again. This signs you out and restarts the reorder.

Why did Chrome move another account back to the top?

If you use Chrome sync, Chrome may put its own account first again after a reorder. Pin mode still opens links in the first account in your Uzero order.

Does Uzero ever see my passwords?

No. You type passwords on Google's own page. Uzero never types, fills, reads or stores them, and it has no server to send them to.

Does Uzero work in private or incognito windows?

No. Uzero does not run in private or incognito windows. On Safari, it never acts in private windows or tabs. Use a regular window for setup, Pin mode and reordering.

Why does the browser ask for access to Google sites?

Uzero needs that access to read your signed-in account list and open Google links in your chosen account. Browser warnings may describe this as permission to read and change data on those sites. Uzero never reads your email, files or calendar content.

Safari may offer Always Allow on Every Website. You can instead allow access to Google sites. The Privacy Policy explains the permissions and local storage.

What happens when I uninstall Uzero?

Your browser deletes Uzero's storage, including the saved account list, order, labels, colors and settings. On Mac, iPhone and iPad, delete the Uzero app to remove the Safari extension. The developer holds no copy. Uninstalling does not undo Google's sign-in order. Google sets that order from the sequence in which you sign in.
