About the message

If you see this message from the App Store, it doesn’t mean anything is wrong with 1Password. Your data is safe.

Try the following steps if 1Password doesn’t start up correctly and you see this message. If one of the steps resolves the issue, you can stop there.

Restart your Mac.
Open the App Store app and choose Store > Sign Out.
Open 1Password. If asked, sign in with the Apple ID that you used to purchase 1Password.
Quit 1Password and drag it from your Applications folder to the Trash. It’s safe to move the 1Password app to the Trash. This will not affect your vaults, saved data, or settings.
Important
Be wary of using an uninstaller app like AppCleaner, AppZapper, CleanApp, and other similar apps. Uninstaller apps prompt you to delete supporting files when moving an app to the Trash, and this can result in accidentally deleting all your 1Password data.
Open the App Store app and install 1Password:
macOS Mojave 10.14 or later
1. Click or your photo in the sidebar.
2. Click next to 1Password in the list.
OS X Yosemite 10.10 or later
1. Click Purchased in the toolbar.
2. Click Install next to 1Password in the list.
