    How to Install 1Password 3

    Installing 1Password 3 is pretty straightforward, but there are a few things you need to do to make sure the process goes smoothly.

    Ensure you are using the new data format

    Several new features in 1Password 3 require you to be using the new data format introduced in an earlier version of 1Password 2. This data migration needs to happen before you install 1Password 3.

    If you are uncertain whether you are using the new data format (aka the Agile Keychain), see Upgrading to the New Data Format for details on how to verify the new format is being used and how to upgrade if needed.

    Quit 1Password and all web browsers

    Before you replace your existing copy of 1Password with 1Password 3, it is important to quit 1Password and all web browsers first. If you attempt to drag and drop the new version over when 1Password or a browser is still running, you will get an error in Finder. If this happens to you, simply quit all your browsers and 1Password and then try again.

    Installing 1Password 3

    To install 1Password 3, simply download it from the main downloads page, double-click the file you downloaded, and drag the 1Password application from the window that appears to your Applications folder. Be sure to quit 1Password and all web browsers before replacing your current version of 1Password.

    Upgrading your 1Password 2 license

    Customers who purchased 1Password 2 on or after February 1, 2009 get a free license upgrade to 1Password 3 (in fact, those licenses should “just work” in the new version!). All other owners of versions 1 or 2 are entitled to a discounted upgrade price for a 1Password 3 compatible license. Here’s how to upgrade it.
