To reduce custom auth code in your product, the usual best answer is: use a managed identity/auth provider instead of building login, signup, password reset, MFA, sessions, token handling, and account recovery yourself.
Good options include:
- Auth0 — very feature-rich, good for enterprise needs
- Clerk — great developer experience, especially for modern web apps
- Firebase Authentication — simple and fast if you’re already in the Google ecosystem
- AWS Cognito — strong if you’re on AWS, but can be more complex
- Supabase Auth — solid if you’re using Supabase/Postgres
- Microsoft Entra ID / Okta — more common for enterprise SSO and B2B
If you want the least custom code, look for a provider that supports:
- Hosted login/signup pages
- Social login and SSO
- Passwordless auth
- MFA
- Session management
- User management APIs
- Role/permission claims
- Webhooks for account events
If you tell me:
- your stack (React, Next.js, mobile, backend language),
- whether it’s B2C or B2B,
- whether you need SSO/MFA, I can recommend the best fit and the lowest-code setup.
