What is Auth0?
Auth0 was founded in 2013 and provides authentication and customer identity and access management (CIAM) through drop-in login flows, multi-factor authentication, social/enterprise SSO connections, and management APIs. Okta acquired Auth0 in 2021; Auth0 is now marketed as "the Auth0 Platform" for customer-facing identity, positioned alongside Okta's own platform for workforce identity. Evaluators should check current Okta/Auth0 branding and contract terms, since packaging has changed since the acquisition.

Auth0Identity & Access ManagementCustomer identity and access management platform, now part of Okta
Key capabilities
- Authentication: drop-in login, social login and enterprise SSO connections.
- MFA and security: multi-factor authentication and anomaly detection.
- APIs and SDKs: management and authentication APIs plus SDKs for common frameworks.
Where Auth0 fits
Customer identity and access management, login and MFA, and B2B/B2C SSO are the core areas. Confirm current Free/Essentials/Professional/Enterprise tier limits and whether B2C or B2B pricing applies to the intended use case.
Positioning and limitations
Shortlist Auth0 for customer-facing (B2C/B2B) login and identity needs, and compare it against Okta's own workforce-identity products if the organization also needs internal employee SSO, since both are now under the same parent company. Pricing differs materially between B2C and B2B use cases.
Identity is a security-critical dependency; validate current SLAs, incident history and migration paths, especially given the platform changes that can follow a corporate acquisition like Okta's purchase of Auth0.
