AuthKit Hosted Login vs Building Your Own Auth UI

Your marketing site may look polished while the sign-in page still looks like a tutorial. Enterprise buyers notice. They also notice whether Okta and social login share one coherent flow.

AuthOne AuthKit gives you a hosted, brandable sign-in and sign-up experience. If you already invested in custom screens, the headless API keeps AuthOne behind your UI.

Choose AuthKit when you want Magic Auth codes, social login (Google, Microsoft, GitHub, Apple), multi-factor authentication (MFA), and enterprise single sign-on (SSO) without owning every edge case in CSS and redirect handling.

You customize colors, logo, and domain. AuthOne keeps session cookies, token lifetimes, and error states consistent across organizations.

Stay headless if your product embeds login inside a complex onboarding wizard, mobile WebView, or white-label experience that cannot tolerate a hosted redirect.

You still call the same AuthOne APIs for users, organizations, and SSO. You own the pixels; AuthOne owns protocol correctness and org policy.

Whether you pick AuthKit or headless, avoid rewriting Security Assertion Markup Language (SAML) parsers and OpenID Connect (OIDC) clients for each IdP. That is the WorkOS-class problem AuthOne solves.

Pick the UI path that matches your brand timeline, then point every enterprise connection at one integration.
