1Password Nightly is a Security & Privacy app for Mac. It needs macOS 12 or later.

About

1Password Nightly is the nightly-channel edition of the 1Password password manager. This Homebrew cask installs the 1Password.app graphical application; it is not a command-line-only package. The supplied package information identifies it as a password manager but does not detail specific features, so this entry does not infer additional capabilities from the 1Password homepage.

  • Installs the macOS app at /Applications/1Password.app.
  • Provides the Nightly variant, rather than the standard or beta cask.
  • Requires macOS 12 or later.
  • Conflicts with the 1password and 1password@beta casks, so those variants cannot be installed alongside this one through Homebrew.

To install, run brew install --cask 1password@nightly. Launch 1Password Nightly from the Applications folder after installation. The cask uses a latest-version download rather than a pinned release. Nightly identifies the selected release channel; the supplied evidence does not specify its release cadence or enumerate differences from the standard or beta editions.

Uninstall command
$ brew uninstall --cask \1password@nightly

A regular uninstall removes the app and keeps its settings and caches.

Deep clean (optional)
$ brew uninstall --zap --cask \1password@nightly

--zap also deletes the settings, caches and other files listed in the Homebrew definition. They can include data shared with other apps and cannot be restored, and it does not guarantee that nothing is left.See which files are removed

Questions

Is 1Password Nightly safe?

1Password Nightly is in Homebrew’s official catalog and has not been disabled. Since September 2026, Homebrew disables apps that fail macOS Gatekeeper checks. The download comes from c.1password.com; Homebrew does not verify a checksum for it. It was installed 31 times through Homebrew in the last 30 days.

How do I completely uninstall 1Password Nightly on a Mac?

Run brew uninstall --cask 1password@nightly. To delete its settings and caches as well, run brew uninstall --zap --cask 1password@nightly. That also deletes 14 files and folders, including ~/Library/Application Support/1Password.

Does 1Password Nightly run on Apple silicon (M1 and later) Macs?

Yes. Homebrew downloads separate builds for Apple silicon and Intel Macs. It needs macOS 12 or later.

Where does 1Password Nightly store its settings and data?

Its data is in ~/Library/Application Support/1Password, ~/Library/Containers/2BUA8C4S2C.com.1password.browser-helper, and ~/Library/Containers/com.1password.1password-launcher. These locations come from Homebrew’s clean-up list.
