Strongbox
Strongbox is a password manager for Mac that helps you store, organize, and use KeePass databases with secure sign-in tools and AutoFill.
What is Strongbox?
Strongbox is a password manager for Mac focused on storing and using KeePass-compatible password databases. It helps people keep logins, secure notes, credit card details, passkeys, and two-factor authentication codes in one place while maintaining control over where that data is stored. The app supports local databases as well as syncing through common cloud storage services or your own server, which makes it useful for users who want flexibility instead of a locked-in password system. On macOS, Strongbox includes features such as AutoFill, biometric unlock with Touch ID where available, password auditing, backup options, and support for hardware keys. It is designed for people who want a native Apple-platform password manager with advanced security controls and compatibility across KeePass-based workflows. Strongbox is published by Mark McGuill.

Safety overview
Status: Mostly safe
Strongbox is legitimate password-management software, but it handles highly sensitive information by design. Access to passwords, secure notes, AutoFill, biometrics, hardware keys, and cloud-connected databases is normal for this kind of app. Keep it only if you use it, protect your database with a strong master password, and make sure you understand where your vault file is stored and backed up before removing the app.
Recommendation: Keep Strongbox if you use it for passwords or KeePass databases on your Mac. Remove it only if you have moved your vault to another password manager or no longer rely on its AutoFill and database access, and make sure your password database and backups are safely stored first.
