Authio Lobby vs Seamless Auth

Authio Lobby provides passwordless sign-in for apps through a hosted interface, SDKs, session features, and widgets for customer IT admins. Sign-in methods include passkeys, magic links, social login, and enterprise SSO using SAML 2.0, OIDC, and SCIM 2.0. The hosted interface can use a custom domain, organization-specific branding, and project-specific email templates. SDKs are listed for Next.js, React, Vue, and Node, with session helpers and edge-runtime JWT verification. Session tools include silent refresh, secure cookie helpers, route gating, and switching organizations within a session. Embeddable widgets let customer admins configure SSO, directory sync, and domain verification within a product. The free Developer tier is for projects under 10,000 MAUs and excludes SSO, SCIM, and Locate. Starter costs $129 a month and Pro costs $449 a month; Enterprise pricing is custom. Authio says GDPR and CCPA compliance is in place and describes its SOC 2 posture as pre-audit readiness, with Type I targeted for 2027-Q1.
