Frequently Asked Questions
Everything you need to know about our SaaS starter kit
Which authentication providers are supported out of the box?
We support JWT-based authentication, Google OAuth2, GitHub OAuth, and magic link email authentication out of the box. The system is built on NextAuth.js/Auth.js, so you can easily add any OAuth provider like Facebook, Twitter, or enterprise SSO providers.
How secure is the authentication implementation?
Very secure! We use industry best practices including bcrypt for password hashing, secure HTTP-only cookies for sessions, CSRF protection, rate limiting on auth endpoints, and secure password reset flows. The implementation follows OWASP security guidelines.
Can I implement custom authentication flows?
Yes! The authentication system is highly customizable. You can implement custom login flows, add additional verification steps, integrate with external identity providers, or build custom multi-factor authentication. The modular architecture makes extensions straightforward.
How does role-based access control (RBAC) work?
Our RBAC system allows you to define roles (admin, user, moderator, etc.) and permissions. Each API endpoint and UI component can check for specific roles or permissions. You can create custom roles and fine-grained permissions as needed for your application.
Is two-factor authentication (2FA) included?
Yes! We include TOTP-based 2FA that works with apps like Google Authenticator and Authy. Users can enable 2FA in their account settings. Backup codes are provided for account recovery. You can make 2FA mandatory for certain roles or organizations.
How are passwords stored and managed?
Passwords are hashed using bcrypt with a high cost factor, never stored in plain text. Password reset tokens are cryptographically secure and time-limited. We enforce password strength requirements and can implement password history to prevent reuse.
Can I add enterprise SSO (SAML/OIDC)?
Yes! While basic SSO providers are included, you can add enterprise SSO using SAML or OpenID Connect. This is perfect for B2B SaaS products that need to integrate with corporate identity providers like Okta, Azure AD, or Google Workspace.
How do session management and token refresh work?
We use a dual-token system with short-lived access tokens (15 minutes) and long-lived refresh tokens (30 days). Tokens are automatically refreshed in the background, so users stay logged in without security compromises. Sessions can be revoked instantly when needed.
