OAuth and Auth Flow Prompts

Auth diagrams are easiest to review when the prompt names the actors, token movement, and alternate paths. These prompts help you generate login and authorization flows that are specific enough for engineering and security review.

Each prompt here is built for AI-native technical diagrams in AIDrawIO. Start from plain English, get draw.io-compatible output, then keep editing as XML or export SVG and PNG.

Copyable prompt blocks

Grab a proven prompt quickly instead of composing from scratch every time.

Refinement-ready

Each prompt includes a follow-up so you can add boundaries, detail, and review context.

Editable outputs

Generated diagrams stay compatible with draw.io workflows instead of locking you into images.

Copyable prompts for oauth and auth flow prompts

Use one prompt as-is, or combine it with the follow-up prompt to add labels, constraints, security detail, or failure handling.

Prompt 1

OAuth 2.0 PKCE web login

Prompt

Create a sequence diagram for OAuth 2.0 PKCE login with browser, frontend app, authorization server, session store, and resource API. Show authorization request, redirect back with code, code exchange, session creation, access token validation, refresh token rotation, and expired refresh token path.

Why this prompt works

It names the real participants and includes the token lifecycle details engineers usually need to review.

Follow-up prompt

Add MFA after primary login and show how logout invalidates both session and refresh token.

Prompt 2

Service-to-service auth with JWT

Prompt

Generate an auth flow diagram for service-to-service API calls: API gateway, auth service, order service, inventory service, and internal key management system. Show token issuance, JWT validation, key rotation, and the failure path when a downstream service rejects an expired token.

Why this prompt works

The prompt covers both the happy path and the operational detail that matters later, such as validation and key rotation.

Follow-up prompt

Add mTLS boundary between internal services and annotate where audit logs are written.

Prompt 3

Password reset and session protection

Prompt

Draw an authentication flow for password reset: user, web app, auth API, email provider, token store, session store, and audit log service. Include reset request, email link generation, token validation, password change, session revocation on other devices, and invalid or expired token error path.

Why this prompt works

It includes the security-sensitive side effects of password reset rather than treating it as a simple email flow.

Follow-up prompt

Add device verification step and show how rate limiting applies to repeated reset attempts.

AWS Architecture Diagram Prompts

These prompts help you generate AWS diagrams faster by naming the key services, traffic paths, and boundaries clearly. Start with one, then use follow-up prompts to add subnets, security controls, or scaling detail.

System Design Diagram Prompts

Use these prompts when you need a system design diagram quickly for interview prep, architecture reviews, or internal docs. Each one names the major components, scaling path, and data flow so the diagram is easy to inspect and refine.

Sequence Diagram Prompts

Sequence diagrams are easiest to generate when the prompt names actors, the order of requests, and any alternate or failure paths. These prompts give you a clean base for auth flows, API interactions, and service-to-service messaging.

ERD Prompts

ERD prompts work best when they name the entities, relationships, and key attributes or constraints. These examples help you generate a clean first-pass schema diagram before you finalize table details.

FAQ

Common questions about oauth and auth flow prompts

What should an OAuth or auth flow prompt include?

Include the actors, token or session movement, message order, and any alternate or failure paths you want to show.

Should auth prompts include refresh, logout, or error cases?

Yes. Those paths are often the most useful part of the diagram for engineering and security review.

Can AIDrawIO generate sequence diagrams for auth flows from plain English?

Yes. AIDrawIO can generate auth and OAuth sequence diagrams from natural-language prompts, then keep them editable afterward.
