A 2026 ranking names Auth0, Microsoft Entra External ID, and Firebase Auth the leading authentication-as-a-service providers.
Cyber Security News ranked ten authentication-as-a-service providers for 2026, scoring developer experience, security depth, and monthly-active-user pricing. Auth0, described as Okta's developer product, led with 9.2, ahead of Microsoft Entra External ID at 8.9 and Google Firebase Auth at 8.7. Amazon Cognito, Stytch, Descope, FusionAuth, Frontegg, Ping Identity, and SuperTokens completed the list. The outlet says the scores are editorial and based on documentation, pricing, and community signal rather than lab tests.
