How to set up automatic backup and synchronization of the local KeePassXC password manager state between a mobile device and a PC?

Using local KeePass password databases ensures maximum privacy, but requires reliable synchronization management between all of the user's working devices. Since there is no single centralized server, the responsibility for delivering the up-to-date version of the file lies with the user themselves.

The first step is to choose a reliable cloud storage or local network drive to host the encrypted database file with the .kdbx extension. It is important to place the file in a secure cloud directory whose access is restricted by two-factor authentication. The KeePassXC application on the computer should be configured to open the file directly from this synchronized folder.

On a mobile device, such as an Android or iOS smartphone, a companion client is installed, such as KeePassDX or Strongbox. These applications configure a direct connection to your cloud storage with the function of automatically downloading the database file every time the application starts or data changes.

To prevent synchronization conflicts, it is strongly recommended to enable the automatic save feature upon record modification in KeePassXC settings and use plugins to integrate with system clocks for precise time synchronization. If changes were made to the same file on different devices prior to synchronization, the application will prompt you to resolve the conflict manually, preserving both versions of the records.
