Heslo Login

Using our FIDO-certified Digital Trust Server Heslo is the fast approach to add secure, FIDO-certified biometrics to a website, application, or service to ensure strong passwordless user authentication. Perfect for banks, universities, healthcare, and high-security institutions who need to onboard users quickly while establishing trust.

Heslo supports all FIDO authentication methods: FIDO Security Keys, biometrics, and the latest platform authenticators such as Windows Hello or TouchID and Face ID.

Supporting FIDO-based passwordless authentication methods on a website or app is complex and requires code to verify cryptographic keys and signatures as well as the WebAuthn attestation and the assertion ceremony.

With Heslo Login, we take care of all this complex code and infrastructure and allow easy integration using OpenID Connect in a just few lines of code.
