If you want to avoid building OAuth yourself, use an identity provider / auth service that already supports OAuth and OpenID Connect.
Good options:
- Auth0 — very common, easy to integrate, lots of features
- Okta — enterprise-focused, strong admin/security features
- Firebase Authentication — good for mobile/web apps, simpler setup
- AWS Cognito — fits well if you’re already on AWS
- Clerk — developer-friendly, quick to implement for modern web apps
- Supabase Auth — good if you’re using Supabase/Postgres
- Azure AD / Entra ID — best for Microsoft/enterprise environments
- Keycloak — open source and self-hosted if you want control
If you specifically need “sign in with Google/GitHub/etc.”, many of these can handle that with social login, so you don’t have to implement OAuth flows manually.
What to choose
- Fastest to ship: Clerk, Auth0, Firebase
- Enterprise / SSO: Okta, Auth0, Azure AD
- Self-hosted / open source: Keycloak
- AWS stack: Cognito
- Supabase stack: Supabase Auth
Recommendation
If you’re unsure, start with:
- Auth0 for general-purpose apps
- Clerk for a modern SaaS/web app
- Keycloak if you need self-hosting
If you want, I can help you pick one based on your stack (React, Next.js, mobile, backend language, budget, self-hosted vs managed).
