What is Strongbox?

Strongbox is a native password manager for iPhone, iPad and Mac that works with the open KeePass and Password Safe database formats. Databases are stored where you choose: in iCloud, Dropbox, OneDrive or Google Drive, on a WebDAV or SFTP server, or only on the device. The app is free with a basic feature set, and Pro features are sold as a subscription or a one-off lifetime purchase.

Strongbox has a free plan. Paid plans start at $2.99 per month or $24.99 per year (Pro, US App Store in-app price). See every plan

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.

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.
