KeePassDX is a lightweight, open-source KeePass-compatible password manager for Android, storing credentials in a local encrypted database file (.kdbx) with support for biometric unlock, autofill, TOTP, and passkeys.
KeePassDX
If you already use KeePassXC on the desktop and want a native Android companion that reads the same .kdbx file, KeePassDX is the cleanest path: it handles kdb and kdbx formats through version 4, supports ChaCha20 and Argon2, and keeps everything local with no account required. The trade-off is the same as any KeePass-family app: syncing your database between devices is your problem, typically solved with a cloud drive or Syncthing. Ad-free, GPL-licensed, and actively maintained. The iOS side of the KeePass ecosystem is a separate story handled by KeePassium.

Why it matters: Strong copyleft keeps every distributed version open. A vendor cannot fold this into a closed product and ship it without releasing their changes.
