KeePassXC stores credentials in an encrypted database file. Its guide describes creating a database, choosing unlock credentials and opening it locally. This gives you control over where the file lives, but it is not the same as a hosted service that manages an account for you.

The official FAQ explains that cloud synchronization is not built in: you can place the database in a folder managed by a separate sync service. Decide who can access that folder and how conflicts or accidental deletion will be handled. A synchronized file is not automatically an independent backup.

A key file can add protection when kept separately from the database. It also adds a recovery dependency: losing it can mean losing access. Preserve safe backup copies of the required credentials and database, and practise opening a non-sensitive sample before trusting your only passwords to the workflow.

Verdict: KeePassXC suits someone willing to manage file storage, backups and device access. It is less suitable if you expect someone else to recover a lost unlock secret. YNIX has reviewed documentation, not audited the encryption or tested recovery, and assigns no security score.
