## Ways to pay less

- **Lifetime Pro for a one-off $99.99** (Lifetime license): Strongbox Pro (Lifetime) costs $99.99 once, as an in-app purchase or as the separate Strongbox Pro app, which supports Family Sharing. A macOS-only build is listed at $44.99. Source: https://apps.apple.com/us/app/strongbox-pro/id1481853033

## Key features

- **KeePass and Password Safe formats:** Reads and writes the open KeePass (KDB and KDBX 3.1 and 4) and Password Safe 3 formats, so an existing database can be opened and stays portable to other apps.
- **Your choice of storage:** Databases can live in iCloud, Dropbox, OneDrive or Google Drive, on a WebDAV or SFTP server, or only on the device, and cloud databases stay usable offline.
- **Face ID, Touch ID and YubiKey:** Unlocks with Face ID or Touch ID, or with a PIN code that has a duress PIN option, and can protect databases with a YubiKey hardware token.
- **Passkeys and one-time codes:** Supports passkeys and generates two-factor TOTP codes, which can be set up from a QR code or entered manually.
- **Password audit:** Checks a database for weak passwords automatically and includes a 'Have I Been Pwned?' check for passwords found in breaches.
- **Browser AutoFill extension:** The Strongbox AutoFill extension for Chrome, Chromium and Firefox fills usernames, passwords and authentication codes from your Strongbox databases.

## Good for

- iPhone, iPad and Mac users who keep passwords in KeePass-format files
- People who want to decide where their password database is stored
- Buyers who prefer a one-off lifetime purchase to a subscription

## Worth knowing

- Strongbox runs on Apple devices only; using the same database elsewhere takes another KeePass-compatible app.
- The App Store listing does not itemize which features are limited to Pro. It describes the free version as a basic feature set.
- The source code is published for inspection, but the developers say it does not meet the OSI definition of open source and do not accept contributions.
- Prices here are from the US App Store; the listing says an upfront purchase option is also described on the Strongbox website.
