Authio Lobby

Overview

Authio Lobby combines hosted passwordless authentication, application SDKs, session management, and embeddable enterprise-identity administration. It suits B2B SaaS teams whose customers need SSO or directory synchronization configured inside the product itself. The central buying question is whether those enterprise controls are required immediately, because the free tier omits them.

Key features

Supported sign-in methods include passkeys, email magic links, SMS OTP, social OAuth, SAML 2.0 SSO, and OIDC SSO. Passkeys use phishing-resistant WebAuthn/FIDO2, while refresh-token rotation and rate-limited authentication endpoints address important account-security risks. Social connections cover Google, Microsoft, Apple, GitHub, Slack, LinkedIn, and Discord.

The hosted interface can run on a custom domain, apply branding by organization, and use project-specific email templates. Custom domains are restricted to Pro and Enterprise, so Starter customers must accept a less fully branded sign-in surface. Magic-link delivery works with Postmark, Resend, SendGrid, Mailgun, or a customer-provided SES transport.

SDKs for Next.js, React, Vue, and Node include session helpers and edge-runtime JWT verification. Silent refresh, secure cookie helpers, route gating, and switching between organizations within one session cover common web-app requirements. The documented stack is focused on those four frameworks, making framework fit an important pre-purchase check.

Embeddable widgets allow a customer’s IT administrator to configure SSO, directory sync, and domain verification without leaving the customer’s application. That is a meaningful advantage for multi-tenant products selling to organizations, rather than a necessary feature for a simple consumer login. Authio describes GDPR and CCPA compliance as in place; its SOC 2 position is pre-audit readiness, with Type I targeted for 2027-Q1.

Pricing

Lobby uses a freemium model, with a 14-day trial and paid plans from $129 per month.

Developer has Community support, Starter has Email support, and Pro adds a priority queue. The free plan’s 10,000-MAU ceiling and exclusion of SSO and SCIM are the main reasons many B2B teams will move directly to paid service.

Platforms

Lobby is offered for Android, iOS, web, and API integrations. Its listed SDKs target Next.js, React, Vue, and Node.

Who it's for

Lobby is a strong fit for B2B SaaS teams that want passwordless access plus customer-managed SAML, OIDC, or SCIM workflows embedded in their own product. It is less suitable for a small app that only needs basic login, or for teams whose framework is outside the documented SDK set and cannot justify checking integration fit.

Pros and cons

Pros

• Broad identity coverage: passkeys, magic links, SMS, social providers, SAML, and OIDC cover both modern passwordless and enterprise requirements.
• Useful multi-tenant administration: embedded SSO, directory-sync, and domain-verification widgets keep customer IT setup inside the product.
• Practical session tooling: silent refresh, route gating, secure cookies, and in-session organization switching reduce recurring integration work.
• Clear growth path: Starter, Pro, and Enterprise add connections, organizations, audit capabilities, and infrastructure controls as deployments expand.

Cons

• Free-tier enterprise gap: Developer excludes SSO, SCIM, and Locate, despite allowing up to 10,000 MAUs.
• Starter branding restriction: custom domains begin only at Pro, limiting white-label control at $129 per month.
• Rising cost for scale: Pro is $449 per month before Enterprise-only requirements such as dedicated infrastructure or residency options.
• Limited published SDK scope: only four web-oriented stacks are named.

Alternatives

Passwordless Authentication Software and Passkey Authentication Software lists are useful when you want to compare categories rather than commit to Lobby’s enterprise model.

• Bitwarden is better when the priority is personal or team password management across unlimited devices and passwords, rather than embedded customer identity.
• FusionAuth is the alternative to consider when a freemium authentication platform with self-hosted options is more important than Lobby’s hosted widgets.
• Okta Customer Identity Cloud suits teams seeking a separately packaged customer-identity service with published Essentials and Professional tiers.
• Trusona is an option for readers focused on its free ATO Protect portal.
• Ory is worth considering when self-hosted or network-based identity deployment is the deciding factor.
• Duo Mobile fits mobile-focused MFA and passwordless authentication needs rather than a full embedded B2B identity stack.
• Hanko is a lower-cost passwordless-oriented alternative, with a free Starter tier and a $29 monthly Pro plan.
• SuperTokens is the choice when self-hosted open-source features at any scale are central to the decision.

Verdict

Choose Authio Lobby if you are building a B2B SaaS product that must combine passwordless login with customer-configured SSO, SCIM, and multi-organization sessions. Its embedded administration and broad sign-in coverage are the strongest reasons to buy. Look elsewhere if you need enterprise identity on a free plan, custom-domain branding at entry level, or a self-hosted open-source deployment.
