Why you need passkeys

arrow icon

400% better conversion
Passkeys boost user conversion by offering simpler, password-free registration and login processes, reducing user frustration and drop-off rates.

clock icon

200% faster logins
Logins are expedited with passkeys, as they use quick biometric authentication, significantly cutting down access time.

lock icon

Data breach protection
With passkeys, the risk of data breaches is greatly reduced, as they securely store authentication details on the user's device, away from vulnerable servers.

lock icon

100% Phishing protection
Passkeys offer absolute protection against phishing attacks. Since there’s no actual password to be stolen, users are safeguarded against common tactics used by hackers, such as fake login pages.

Open Source

Avoid vendor lock-in. Passkey API is an open source project – for transparency, trust, and longevity. Driven by the community.

Passkeys, you can play around with them on passkeys.io but hopefully you will see them everywhere soon. The web is bugged in that we didn't have a sane auth layer. This is the solution. The web will be 10x better with effortless secure auhtentication.
