Core Configuration

• BETTER_AUTH_SECRET: Encryption secret (min 32 chars).
• BETTER_AUTH_URL: Base URL of your application (must match exactly).
• baseURL/secret: Only define in config if env vars are NOT set.

Database & Adapters

• Pass pg.Pool, mysql2 pool, etc., for direct connections.
• Better Auth uses adapter model names, NOT underlying table names (e.g., use user instead of users if using Prisma).

Session Management

1. Secondary Storage: Sessions go here by default if defined.
2. Stateless Mode: No DB + cookieCache.
3. : (default), , .
