Completely Uninstalling 1Password

If something is going wrong and you want to start with a fresh installation, or you are selling your Mac, you may need to completely uninstall 1Password and all its support files.

Using 1Password Uninstaller

The easiest way is to use the uninstaller application.

1Password Uninstaller App

You can download it here: Download 1Password Uninstaller

Simply click the Uninstall 1Password button and all 1Password files will be deleted. You will see Complete message at the end:

1Password Uninstaller Completed

By default the application preferences and your data file will not be removed. You can send them to Trash by selecting the checkboxes. Please note that if you delete these files by mistake, you can still recover them from the Trash.

Uninstalling 1Password Manually

You can also remove 1Password manually. 1Password consists of several pieces:

The following steps detail how to remove or deal with each of these items.

Unless otherwise specified, all locations are shown relative to your OS X account’s “home”. “Home” is your own account’s main folder. In the Finder’s sidebar it’s represented by an icon of a house with your account’s name beside it… that’s where the “home” reference comes from.

Removing the Browser Extensions

There are two kinds of extensions provided with 1Password for your browsers – externally activated and those native to the browser. The distinction is if the 1Password application is fully in control of the extension’s installation and uninstallation, or if the browser itself did everything to include a downloaded extension for an installation, and thus needs to be used again for any uninstall. Native browser extensions use support files and locations that only the browser itself knows about, and knows how to fully remove.

To remove the externally activated extensions:

To remove the native extensions:

Now that the 1Password extension support has been removed, be sure to relaunch any open browsers to complete this section.

Removing Scripting Addition

Move the Library > ScriptingAdditions > 1Password Addition.osax to the Trash. If your system is running Leopard, the file is named 1Password Addition Leopard.osax instead and should likewise be moved to the Trash.

Removing the 1Password Application

Move the 1Password.app from your system’s Applications folder (or wherever you may have installed it) to the Trash.

Removing Application Support Files

Move the Library > Application Support > 1Password folder to the Trash.

Removing the Data File

1Password’s data file is stored in the Library > Application Support > 1Password folder by default and was therefore likely deleted in the previous step. However, if you stored the file elsewhere on your hard drive, you can use Apple’s Spotlight facility to search for 1Password.agilekeychain and delete that file.

IMPORTANT: This file contains all the information you added to 1Password and it will be lost if you delete this file.

IMPORTANT: If your data file is currently located in a Dropbox-monitored folder, deleting it on this system will delete it from all other systems that are syncing with the same Dropbox account. This will impact other copies of 1Password for Mac, 1Password for Windows and the 1Password mobile apps that are using the same Dropbox account as a sync method.

Removing Data File Backups

1Password’s data file backups are stored in the Library > Application Support > 1Password folder by default and were therefore already removed when you deleted that folder. If you migrated from an older version of 1Password, you can also check for and delete the Library > Keychains > backup folder. If you elected to store your 1Password data file backups in a non-default location you’ll need to search for them and move them to the Trash: they will have an extension of .agilekeychain_backup.

Removing Application Preferences

Move the Library > Preferences > ws.agile.1Password.plist file to the Trash. You may also find in the same location a file named ws.agile.-PasswordThumbs.plist. Move it to the Trash too.

Removing Log Files

Move the Library > Logs > 1Password folder to the Trash.

Removing Cache Files

From the Library > Caches folder, move the 1Password, ws.agile.1Password, ws.agile.-PasswordThumbs, ws.agile.-PasswordUpdater and ws.agile.1PasswordUpdater folders to the Trash. Some of these may not exist in your account.

Removing 1Password as a Login Items

Have you added the 1Password application to your OS X account’s “Login Items” list? Follow the menu options of Apple > System Preferences > Accounts > Login Items to verify and remove 1Password if it is listed there.

Removing 1PasswordAgent LaunchAgent

Move the Library > LaunchAgents > ws.agile.1PasswordAgent.plist file to the Trash and then restart your Mac.
