When to Use This Skill
- Implementing authentication in a TypeScript project
- Setting up OAuth providers (Google, GitHub, Microsoft, etc.)
- Configuring database adapters (Prisma, Drizzle, etc.)
- Adding 2FA, passkeys, or magic links
- Managing sessions and cookies
- Integrating with Next.js, SvelteKit, or other frameworks
- Questions about auth patterns and best practices
How to Navigate
- Start with
references/introduction.mdxfor overview - For setup: Read
references/installation.mdx - For auth methods: Browse
references/authentication/ - For database: Check
references/adapters/ - For advanced features: See
references/plugins/ - For framework integration: Use
references/integrations/
