Seamless authentication; skip the OAuth flows

Unified removes the complexity of signing-in your users into your application.

Redirect your users to one unified authentication URL. They sign-in, you get back their verified email and name. No tokens, no sessions, no custom OAuth2 flows, no API docs to read.

Add SAML SSO to your application

Let enterprise customers sign in through their own directory. Their IT team controls who gets access, and removes it during offboarding without a request to your support team.

Google Workspace Directory, JumpCloud, Microsoft Entra ID, and Okta are supported.

Business Login, without the overhead

Simple auth redirect

No SDKs - just redirect users to a single URL and receive their verified emails and name in the callback. Sample code provided for React, Vue, and Angular, plus stock provider logos, button colors and names.

Comprehensive auth flows

No OAuth2 handshakes. Unified handles every OAuth2 flow variation, so you don't have to. Built on OpenID Connect (OIDC), with standard OAuth2 fallback for providers that don't support it.

OAuth2 registration guides

Step-by-step guides to get your own OAuth 2 credentials fast.

Enterprise-grade security

SOC 2 compliant. No data storage or caching. Keep API credentials (client secrets, API tokens) locked down in your own secrets manager (AWS, GCP, Azure, or HashiCorp Vault).

Authorize across 237 identity providers

From Google and Microsoft to Slack, Salesforce, QuickBooks, and BambooHR. Unified.to supports more identity providers than any other solution.

No access token storage

Unified.to returns verified identity info, without requiring token handling or session management.
