How to verify the authenticity of the 1Password app

If you manually download the 1Password app, you can verify its signature to confirm that it’s authentic.

To confirm the authenticity of 1Password, the app and all its updates are digitally signed and offered exclusively through the official app store for your operating system or the 1Password downloads page. Always get 1Password updates from one of these sources, and always check these sources to make sure that you have the latest version.

App store downloads and updates are automatically verified

The digital signature of the 1Password app is automatically verified before installation:

  • If you install 1Password or an update from the official app store* for your operating system
  • If 1Password updates itself

* Official app stores include: Mac App Store, iOS App Store, and Google Play.

Manual downloads are partially verified by your operating system

If you manually download 1Password from the 1Password downloads page, your operating system will verify that it comes from a known developer and hasn’t been tampered with.

To confirm that the installer is authentic

To confirm that the installer is authentic, you can verify the digital signature before installation.

  1. Unzip the installer that you downloaded.

  2. Open Terminal, which is in the Utilities folder of your Applications folder.

  3. Copy and paste the following command, followed by the path to “1Password”. For example, if the installer is in your Downloads folder:

     spctl --assess -vv ~/Downloads/1Password\
  4. Press Return.

If the command returns the following, the code signature of the 1Password installer is valid:

    /Users/<username>/Downloads/1Password accepted
	source=Notarized Developer ID
	origin=Developer ID Application: AgileBits Inc. (2BUA8C4S2C)

The installer automatically verifies the files it downloads. If any file has an issue, installation stops without changes to your system, and you’ll see a message that the installer encountered an error.

  1. Right-click the 1Password setup executable (.exe) file and choose Properties.

  2. Select the Digital Signatures tab.

  3. Select “Agilebits”, then click Details. If you see a different signer, or the installer isn’t signed, don’t install the app.

  4. Make sure you see “This digital signature is OK”. Otherwise, the digital signature of the app is invalid, and you shouldn’t install it.

  5. Click View Certificate, then select the Details tab and scroll down.

  6. Make sure that the thumbprint in the installer matches the following thumbprint from the current AgileBits certificate. If they match, the signature is verified; install the app.
