KeePassium Password Manager

KeePassium is a KeePass-compatible password manager for iOS. It offers automatic database synchronization, respect to privacy and premium user experience.

KeePassium is a commercial open source app. The "commercial" part gives you a well-maintained app with premium support. The "open source" part gives you the transparency expected from a password manager: you can personally audit the code and build the app you can trust.

Automatic sync

KeePassium relies on OS-provided integration with storage providers, and supports most providers that appear in iOS Files app.

• Full support (files are automatically downloaded and uploaded when changed): iCloud Drive, Box, Dropbox, Google Drive, OneDrive, Resilio Sync, Nextcloud (with hiccups), SFTP / WebDAV (via third-party apps)
• Limited support (no background sync, files have to be imported and exported manually): Mega, Cryptomator (it supports only import/export operations)
• Not tested yet: ownCloud, Tresorit

If automatic sync does not work for you, please make sure the cloud provider app can work in background (device settings — Dropbox/OneDrive/... — Background App Refresh = Enabled).

Password AutoFill

To fill your passwords easily and quickly, enable AutoFill feature: device settings — Passwords & Accounts — AutoFill Passwords — select KeePassium in the list.

App and Data Protection

KeePassium has multi-layer protection from unauthorized access.

• App Lock protects the app itself, by covering any in-app screens. This way, only you can see the unlocked database, the list of databases, or change app settings.
• Database Lock closes all opened databases after a timeout, or after a failed AppLock attempt. It also removes any remembered master keys from keychain.
• Encryption protects the contents of database files. The app relies on CommonCrypto library (for AES and SHA) and time-proven reference implementations of crypto algorithms (see Credits).

By default, AppLock requires a passcode (of any complexity). For convenience, you can configure the app to use Face ID/Touch ID instead.

Installation

KeePassium is available on the App Store. Current beta can be installed via TestFlight.

To build your own binary, download the project and open it in Xcode 10.2 (or above). All the dependencies are already included.

Is it free?

Yes, KeePassium can be used free of charge (gratis) and is also free as in speech (libre). An optional premium subscription enables a few convenience and time-saving features, and supports the project.

But I can just... Yes, you can take the source code and build your personal premium version for free (gratis). Feel free to do so, but please be nice and don't request premium support for personal builds. Also, if you delegate this to a freelancer, please make sure you can trust them.
