Auth0 is a leading identity-as-a-service platform providing authentication and authorization for over 18,000 customers and billions of login transactions monthly. Now part of Okta, Auth0 offers universal login, social connections, multi-factor authentication, passwordless login, and machine-to-machine authentication through developer-friendly APIs and SDKs. The platform handles the complexity of identity management including SSO, RBAC, SAML federation, and compliance with security standards, allowing developers to implement secure authentication without building it from scratch.
Auth0 outages are particularly impactful because they directly prevent users from logging into applications. Common causes include authentication API latency spikes during peak login hours, tenant isolation failures on the shared infrastructure, database replication lag affecting user profile lookups, and rate limiting enforcement errors that incorrectly block legitimate login attempts. Social connection outages (Google, GitHub, Microsoft login) often stem from upstream provider issues rather than Auth0 infrastructure failures.
When Auth0 goes down, users cannot log into any application that relies on Auth0 for authentication — effectively locking users out of potentially thousands of applications simultaneously. New user registrations fail, token refresh flows break causing session expirations, and MFA verification becomes unavailable. For SaaS applications where Auth0 powers the login page, an outage means zero new user access until service resumes. Machine-to-machine tokens also fail, breaking API integrations between services.
Use this page to check Auth0 availability. Auth0 operates region-specific deployments, so US, EU, and AU regions can experience independent outages. Check status.auth0.com for per-region status information. If users report login failures across your application, Auth0 should be your first checkpoint.
Login failures may result from Auth0 outages, misconfigured application settings, expired client secrets, or blocked social connection providers. Check if the issue affects all login methods or just specific ones like Google or GitHub login. If all methods fail simultaneously, it is likely an Auth0 platform issue rather than a configuration problem.
Existing sessions with valid tokens continue working until tokens expire. However, token refresh flows will fail during an Auth0 outage, causing sessions to eventually expire. New logins are impossible. Applications with short token lifetimes will be more severely affected because sessions expire and cannot be renewed during the outage window.
Use longer token lifetimes for refresh tokens to extend session validity during outages. Implement graceful degradation that allows limited functionality for users with expired tokens. Cache user profile data locally rather than fetching from Auth0 on every request. Consider implementing a fallback authentication mechanism for critical applications.
