If you’re upgrading from 1Password 3, you’ll need to remove the 1Password 3 extension. But first make sure all your data is safely stored in the 1Password app.
You don’t need to follow these steps if you’re upgrading from 1Password 4 or later. These steps are only for 1Password 3.
Verify that your Logins have been saved in 1Password
To make sure 1Password has all your data:
Step 1: Open and unlock 1Password
Open the 1Password 3 main app and unlock by entering your Master Password.
You can’t use 1Password 4 or 5 with the 1Password 3 extension.
Step 2: Save a new Login item in your browser
- Open your browser.
- Visit the login page of a website. The website doesn’t matter. Any login page will do. The username and password don’t have to be real, either, because you’re not actually going to sign in.
- Enter anything for the username and password on the website’s login page, but DO NOT try to sign in.
- Click in your browser’s toolbar to open the 1Password extension.
- Click the
+button in the top right corner of the 1Password extension.
- Enter a name for the login, like “Ready to uninstall”.
- Click Save in the top right corner.
Step 3: Verify the Login in the main 1Password app
Switch back to the 1Password 3 main app, and verify that the Login you just saved in your web browser shows up in list of Logins in the main app.
- If the Login you created in the browser shows up in the main app, quit 1Password 3, and uninstall the 1Password 3 extension by following the steps below.
- If the Login you created in the browser does not show up in the main app, send a diagnostics report to 1Password Support.
