What KeePassXC is

KeePassXC is a free, open-source password manager that stores sensitive information in an encrypted database file. The file can contain usernames, passwords, URLs, attachments, and notes, and may be kept offline or placed in a private or public cloud location. KeePassXC does not synchronize the database itself; when it is in a shared cloud folder, a separate sync service can handle synchronization.

The desktop app runs on Windows, macOS, and Linux. Its browser extension autofills passwords from a local KeePassXC installation in Firefox, Chrome, and Edge. The database uses AES256 or Twofish encryption, with a configurable number of key transformations to strengthen the master password. A key file or YubiKey can further protect the master key. KeePassXC supports passkeys and secure sharing, and its SSH Agent integration can add database keys to a running agent while unlocked and remove them when locked. It supports KeePass 2.x KDBX 3.1 and KDBX 4 formats and can open and upgrade KDBX 2 files. The KeePassXC Team is based in Weimar, Germany.

Getting started

Download KeePassXC for Windows, macOS, or Linux from its website.

If you want synchronization, store the database in a shared cloud folder and use your chosen sync service.
