KeePassXC’s basic functions are pretty similar to commercial password managers on the market. Users create their own database with a strong master password, and their sensitive data (usernames and passwords) are encrypted using AES-256 encryption, within that database. Users will need to store this database someplace accessible for their devices – it could be stored locally if they only want to use the password manager on one device, but would need to be on a cloud storage service to be accessed from multiple devices.
