Developers + AI agents

Copy this for your AI agent.

Use this starter prompt in Cursor, ChatGPT, Claude, Codex or OpenCode to plan a safer sign-in experience. Copying does not connect accounts or run code.

Starter prompt (customize for your project)

Act as my AI development agent. Help me evaluate AUTH2 (https://auth2.app/) for secure, low-friction customer sign-in on my website or app. Ask for my stack, existing sign-in system and desired methods (Apple, Google, phone one-time codes or email magic links), without requesting passwords, API keys or customer data. Review only repositories and environments I authorize. Propose a minimal integration plan covering OAuth/OIDC and PKCE where applicable, redirect allowlists, account linking, recovery, session security, tenant isolation, tests and rollback. Confirm any AUTH2 API, SDK, OIDC issuer or MCP endpoint is actually published and working before attempting a call; do not invent interfaces or claim the service is live. If direct integration is not verified, prepare a brief for support@auth2.app with my requirements and questions. Do not deploy, change settings or send data externally without my approval.

Familiar ways to sign in

The setup is taken care of

We handle the integration and testing. Add ongoing care when you want someone to look after maintenance and support, too.

Simple to start. Yours to manage.

Can I set up my account myself?

Yes. AUTH2 brings account setup and sign-in options together in one place, so you can manage the basics yourself. Help is available for more involved integrations.

Can I use my existing website or app?

Start with the platform you already use. Available sign-in methods depend on your provider and configuration. Confirm compatibility before connecting a production system.

Who controls the setup and deployment?

You control your project, choose what to enable, and approve production changes. More advanced integrations may need additional security checks or technical help.

Your sign-in.
Your setup.

Set up your AUTH2 account, choose your sign-in options, and manage your website or app from one place.
