Strongbox
Strongbox is a macOS password manager for opening, editing, and syncing KeePass-compatible vaults across your devices.
What is Strongbox?
Strongbox is a password manager for macOS that helps you store, organize, and fill passwords, passkeys, notes, and other sensitive information in KeePass-compatible databases. It is designed for people who want a native Apple experience while keeping control of their vault files in an open database format. Common uses include managing website logins, software licenses, secure notes, and shared or personal credential collections. Strongbox supports local storage as well as common sync locations so the same database can be used across Mac, iPhone, and iPad workflows. It also integrates with password autofill on Mac, making it easier to sign in through supported browsers and apps. Published by Mark McGuill, it fits users who want a dedicated security and privacy tool rather than a general productivity app.

Safety overview
Status: Safe
Strongbox is legitimate password-management software, so access to your stored credentials and secure notes is central to how it works. Some features may interact with autofill, cloud storage, hardware security keys, or Apple security options, which is normal for this kind of app. The main practical precaution is to protect your master password, keep backups of your vault database, and be careful when enabling sync so you always know where your encrypted data is stored.
Recommendation: Keep Strongbox if you use it to manage passwords or passkeys. Remove it only if you have migrated your vaults to another password manager and no longer need access to its databases, and make sure your encrypted vault files are backed up before uninstalling.
