What OneKeePass is

OneKeePass is a free, open-source password manager for KeePass-compatible KDBX 4.x databases. It stores passwords and other sensitive information in an encrypted file that can remain local or use a storage provider you choose. The app works fully offline, with databases protected by a master key and encrypted using AES-256 or ChaCha20. Entries can be organized by type, category, or group tree, with custom fields and file attachments. It includes password and Diceware passphrase generation, TOTP, and passkey support. Databases can open directly from SFTP and WebDAV servers. A browser extension connects to the desktop app for autofill and passkeys in Firefox, Chrome, and Brave. Mobile apps provide autofill, biometric unlock, PIN protection, and passkeys on iOS 17+ and Android 14+. Desktop features include Touch ID, Windows Hello, macOS Auto-Type, and SSH agent modes. OneKeePass is GPLv3 licensed and says it collects neither personally identifiable information nor database contents.
