Top reviewed
Among the most-reviewed tools, teams split between all-in-one backend platforms like Firebase, developer-friendly hosted auth such as Clerk, and enterprise-ready identity stacks like Auth0. Common priorities are fast signup/login flows, social and SSO support, MFA, session management, and org-level permissions, with stronger products differentiating on multi-tenant B2B workflows, passwordless options, and how much backend infrastructure they bundle.
