What is it?

KeePassDX is a password and passkey manager for Android. All credentials live in a single encrypted database file in KeePass format, unlocked with a master password, a keyfile, or biometrics. Entries are organised into group trees, and each entry keeps a history of its changes.

The app supports Android autofill for filling passwords into forms, along with a custom keyboard called Magikeyboard for filling any field. It also manages HOTP and TOTP one-time codes for two-factor authentication and stores passkey private keys locally. Both .kdb and .kdbx files (versions 1 to 4) are supported, with AES, Twofish, ChaCha20 and Argon2 algorithms, and the files are designed to work with other KeePass-compatible clients such as KeePassXC and KeeWeb.

The project is open source under GPL-3.0, ad-free, and a fork of KeePassDroid. The app is distributed through F-Droid, Google Play, IzzyOnDroid and GitHub releases.
