Keeper wins CHIP.de password manager test for a fourth year with quantum-safe encryption

Keeper retains CHIP.de’s top password manager rating, combining strong usability with quantum-safe encryption designed to prepare for future threats.

Keeper has once again emerged as CHIP.de’s test winner in the password manager category, with the magazine giving it an overall score of 1.3 and praising both its security design and ease of use. The review also notes that Keeper has now finished first for the fourth year in a row, underlining its consistency in a field where trust and reliability matter more than flashy additions. According to CHIP.de, the service stands out not only for its overall result but also for one of the more forward-looking protections in the market: quantum-safe encryption.

That feature is intended as preparation for a risk that is not yet immediate but is increasingly discussed in security circles. CHIP.de explains that quantum computers are not presently a practical threat to conventional password encryption, but that some providers are already starting to adapt. Keeper is among them, and the magazine says the protection works in the background without adding any extra steps for users. In practice, that means the service is positioned to keep credentials protected if future advances in quantum computing make current defences easier to undermine.

Beyond that future-facing layer, the review describes a mature and well-rounded product. Keeper includes the expected basics, such as a strong password generator, export options, support for passkeys and security keys, password breach alerts and encrypted metadata. It also offers emergency access and file attachments, while maintaining a strong security model built around a cloud-based service rather than a locally stored password file. CHIP.de says that local backups are possible, but also points out that the free version does not give a strong sense of how the product performs in day-to-day use.

Where Keeper appears to win most clearly is usability. CHIP.de says the programme scored top marks or the highest available grade in every area of its handling and interface assessment, and it performed well across Windows, Android and iOS. Synchronisation between devices was described as smooth and dependable. In the broader comparison, Keeper finished ahead of rivals including Bitwarden, 1Password and NordPass, although the review also noted gaps such as the absence of email aliasing and the lack of synchronisation via alternative cloud sources. Keeper’s own blog separately celebrated the CHIP result as its fourth consecutive win, while Tom’s Guide and other independent reviews have similarly highlighted its zero-knowledge model, AES-256 encryption and strong administrative controls.
