itsme®-level security, in your own app
nextAuth consists of two components: an SDK that sits inside your app, and a server that runs in your own environment. No data leaves your infrastructure.

Why choose nextAuth?
Authentication your users won't abandon
Enable your users to log into your mobile and web applications with a biometric scan on their mobile phone, with a PIN code as a fallback method. Reduce authentication complexity, cut login time and slash your drop-off rate.
KYC
Security rooted in the device
Embed our SDK into your app to turn the user's phone into a secure device. The private key never leaves the phone, so credentials can't be stolen, copied, or phished. This makes impersonation by bad actors impossible.
KYC
Seamless integration in your own environment
The nextAuth server runs either on-premise infrastructure or on your cloud. Our RESTful API and integrated IdP via SAML or OIDC guarantee seamless integration into your applications and your systems.
KYC
Seamless security for HR and employees
SD Worx implemented a stronger authentication approach to protect sensitive HR data across 17 countries, ensuring a seamless employee experience while enabling effortless international scalability.
