AuthPass is a free open-source password manager built with Flutter, compatible with KeePass KDBX files. See features, pricing, and pros and cons.
AuthPass is a free, open-source password manager built with Google's Flutter framework, which lets it run natively across Windows, macOS, Linux, Android, iOS, and the web from a single codebase. It was first released around September 2019 by Herbert Poul, a freelance developer based in Austria, and has since been maintained with help from open-source contributors.
The defining characteristic of AuthPass is that it works directly with KeePass-format database files, specifically KDBX 3 and KDBX 4. This means users are not locked into a proprietary vault format controlled by a single vendor; the same encrypted database file can be opened in AuthPass, KeePassXC, or other KeePass-compatible clients.
The project's source code is publicly available on GitHub under the GPL-3.0 license, and the app is distributed through the App Store, Google Play, and direct downloads for desktop platforms.
AuthPass loads and decrypts KDBX files using a master password and, optionally, a key file for an added layer of protection. Once unlocked, the app can store the master password in the device's secure keystore or keychain and let users unlock the vault afterward with a fingerprint or face scan.
Because AuthPass does not run its own proprietary sync service by default, it integrates with existing cloud storage providers, including Google Drive, Dropbox, and WebDAV-compatible services such as Nextcloud and ownCloud, so vaults stay synchronized across devices.
Other features include password generation, organization of entries into groups and tags, attachment support inherited from the KDBX format, and a consistent interface across desktop, mobile, and web so users have the same experience regardless of platform.
AuthPass itself is free and open-source software with no license fee, subscription, or paid tier for the core app; anyone can download the source from GitHub and build or run it without payment.
There are no publicly listed pricing plans because AuthPass does not operate a commercial SaaS pricing model in the way closed-source competitors do; its sustainability instead comes from voluntary community contributions and the goodwill of its maintainers.
Users who want cloud sync typically bring their own storage account (Google Drive, Dropbox, or a WebDAV server), which may carry its own separate cost from the storage provider, but this is unrelated to AuthPass's own pricing.
