Description

KeePassXC is a modern, open-source password manager that allows users to store and manage their credentials in a fully encrypted local database. Unlike cloud-based solutions, KeePassXC keeps all data under the user’s control, using AES-256 encryption to secure the password database. This approach ensures that no third party, including the developers, can access your passwords, making it a preferred option for those who prioritise privacy and data sovereignty.

The software is cross-platform, supporting Windows, macOS, and Linux, and offers features such as a built-in password generator, browser integration, and support for hardware security keys like YubiKey. KeePassXC is actively developed and maintained by a small team, with regular updates and improvements. Recent releases have included new features like a Proton Pass importer, improved password strength indicators, and enhanced usability options.

KeePassXC’s offline nature means users are responsible for backing up and syncing their database files, which can be done manually or via secure cloud storage. While this requires more technical effort than cloud-based managers, it also eliminates the risk of data breaches or unauthorised access from third-party servers. The platform is highly customisable, with support for plugins and advanced security options, but its complexity may be a barrier for less technical users.

In terms of security, KeePassXC has not been immune to scrutiny. In 2025, a potential vulnerability related to browser extension clickjacking was reported, but the KeePassXC team clarified that the risk was mitigated by the platform’s design, which requires local access to the database file. A few months later a fix was released to further protect users against malicious websites. The project’s transparency and active community support further reinforce its reputation as a secure and reliable password manager.
