For sign-ups and logins, first impressions matter
Deliver more secure, seamless, and fully customizable sign-up and login experiences for your consumer app—at any scale.

Win and retain customers with a trusted identity solution
Auth0 combines customer identity access management (CIAM) with fully branded experiences—down to the pixel. Whatever your team is building, turn your first-time visitors into repeat users.
Get continuous protection with a seamless experience
Security shouldn’t add friction. Customers get fast, passwordless logins, while built-in defenses like adaptive MFA, bot detection, and standards-based security keep them safe. Plus, Auth0 monitors in-session activity and prompts for a login challenge only when a risk is detected.

Frequently asked questions
How can I improve conversion rates and user retention?
Auth0 helps reduce friction at critical moments like registration and login by supporting options such as social login, passwordless authentication, and passkeys. By minimizing the steps required to get started and avoiding unnecessary challenges, you can improve sign-up completion rates and create smoother user experiences that support ongoing engagement.
How does Auth0 help address security and privacy requirements like GDPR and CCPA?
Auth0 provides capabilities that support compliance with regulations like GDPR and CCPA, including more secure data handling, encryption, user data management, and audit logging. You can implement features such as user consent flows and account deletion to meet requirements like the right to be forgotten.
How does Auth0 secure user sessions beyond login?
Auth0 continuously evaluates risk across the entire user session—not just at authentication. It monitors signals like device behavior, and anomalies in real time, and can trigger step-up authentication (such as MFA) when risk changes. This allows you to protect sensitive actions without adding unnecessary friction to every interaction.
How can I customize authentication and user journeys for my application?
Auth0 provides extensibility through Actions, allowing you to customize authentication flows end-to-end. You can control sign-up, login, and post-login behavior, apply conditional access policies, and orchestrate user journeys without rebuilding core identity infrastructure.
How do I manage identity consistently across multiple applications and channels?
Auth0 acts as a centralized identity layer that can be shared across your applications, APIs, and devices. It supports standards like OAuth 2.0 and OpenID Connect, enabling consistent authentication, authorization, and session management across web, mobile, and backend services.
How can I reduce sign-up and login friction while maintaining strong security?
Auth0 supports modern authentication methods like passkeys, passwordless login, and social identity providers, allowing users to authenticate quickly. At the same time, adaptive MFA and risk-based policies ensure additional verification is only required when necessary.
How does Auth0 integrate with my existing systems and architecture?
Auth0 integrates with your applications, APIs, and user stores using standards like OAuth 2.0 and OpenID Connect, along with SDKs for common platforms. You can connect to your existing user database using custom database connections, allowing Auth0 to authenticate users against your current data store or migrate users over time. This makes it possible to introduce Auth0 without replacing your existing setup all at once.
How does progressive profiling work in Auth0?
Auth0 enables you to collect user attributes over time instead of requiring everything upfront. You can request additional information at relevant points in the user journey—such as after sign-up or during key interactions—so you reduce friction early while still building richer user profiles for personalization.
