Usage

Important
For secure database setup use the KeePassXC GUI.

keepassxc-cli provides the ability to query and modify the entries of a KeePass database, directly from the command line. This document shows a simple set of commands. Presented example commands cover most common use cases needed to create new db, add entries, list and remove entries from a example database.

Specific database entries need to be set using the KeePassXC GUI. Generating of (OTP) one-time passwords works.

Tip
Use the KeePassXC GUI to add a Base32 secret to the database entry.

Tips

Passwordless authentication

Depending on the given situation it might be useful to authenticate using only a ~/*.keyx file, without the need of keyboard-interactive user authentication. For example, testing in automated environements.

Generate a random key file named keepass.keyx in current directory, generate using openssl:

user $openssl rand -out keepass.keyx 256

Now keepassxc-cli db-create the database, and set keyfile to --set-key-file keepass.keyx, using applications default Passwords.kdbx database name:

user $keepassxc-cli db-create --set-key-file keepass.keyx Passwords.kdbx
Successfully created new database.

Display database technical information using the keepassxc-cli db-info command, use --key-file keepass.keyx to authenticate and ask --no-password:

user $keepassxc-cli db-info Passwords.kdbx --key-file keepass.keyx --no-password
