Better Auth Best Practices

Better Auth provides secure authentication for TypeScript applications by supporting email/password, OAuth, and magic links. It uses type safety and database adapters to manage user sessions and credentials efficiently.

Adding Google Sign-In to a Next.js app is done using Better Auth's social provider capabilities. This integration connects OAuth credentials to your existing user database while maintaining client-server type inference.

Yes, Better Auth supports existing database setups through flexible database adapters. This maps user accounts, sessions, and linked social profiles directly to your current schema structure.

Client-server type inference in TypeScript authentication ensures session data and user objects are strictly typed across the network boundary. Better Auth automatically infers these types from server configuration to prevent client-side runtime errors.

Handle advanced session management and account linking by configuring Better Auth's plugins and security settings. This manages multiple OAuth providers per user, customizes session expiration, and implements specific error handling logic.
