How does Auth0 handle complex B2B user roles and permissions?
Auth0 supports Role-Based Access Control (RBAC) and Fine-Grained Authorization (FGA) out of the box. Teams can define granular access permissions across multi-tenant environments, helping ensure users and connected systems only reach the specific APIs, data, and workflows assigned to their role.
Can we customize and white-label the login experience per customer?
Yes. Auth0 supports full white-labeling and domain customization per enterprise account. Teams can deliver custom branding, localized login screens, and distinct authentication policies tailored to each customer organization's requirements.
How does Auth0 help our platform pass enterprise security audits?
Auth0 supports compliance with standards including SOC 2 Type II, ISO 27001, HIPAA, and GDPR. Built-in audit logging, credential protection, and centralized access controls give security teams the visibility and documentation needed to pass customer security reviews.
Can we connect Auth0 to our existing database or custom identity store?
Yes. Auth0 supports custom database connections and legacy system integrations. Teams can migrate users gradually or connect to existing user stores without forcing end users to reset passwords or disrupting current application workflows.
How does Auth0 support machine-to-machine (M2M) and API security?
Auth0 provides dedicated API authorization using OAuth 2.0 standards and JSON Web Tokens (JWTs). Teams can help secure communication between microservices, external partner APIs, and automated tools while enforcing strict rate limits and scopes.
Does Auth0 support B2B social login?
Yes, Auth0 allows B2B SaaS applications to offer social login options, such as LinkedIn or Google, alongside enterprise SSO. This flexibility is ideal for B2B products that cater to smaller businesses or freelancers who may not have a centralized corporate identity provider, helping ensure a frictionless signup and login experience for all user segments.
