AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
This skill provides a structured, non-interactive workflow for integrating authentication into a Convex application. It focuses on avoiding common pitfalls such as interactive CLI hangs and misconfigured auth.config.ts files. The process covers package installation, headless generation of cryptographic keys, environment variable deployment, and client-side wiring, ensuring a robust and functional authentication flow.
What it does
- Installs and configures @convex-dev/auth for Convex projects.
- Generates JWT keys headlessly using jose to avoid interactive CLI issues.
- Sets up required environment variables for deployment via secure methods.
- Writes the critical auth.config.ts file to prevent silent authentication failures.
- Wires client-side providers and UI components for sign-in functionality.
- Verifies the complete authentication round-trip.
When to use it
- When adding authentication to a new or existing Convex application.
- When you need to implement passkey, OAuth, or password-based authentication.
- When working in headless or CI environments where interactive CLI wizards fail.
- When you want to ensure the auth.config.ts file is correctly wired to avoid silent sign-out bugs.
Advantages
- Prevents common authentication configuration errors.
- Enables automated, non-interactive setup suitable for CI/CD pipelines.
- Ensures consistent and secure handling of cryptographic keys.
- Reduces development time by providing a clear, step-by-step integration path.
Usage examples
- “Add passkey authentication to my current Convex project.”
- The agent will install the necessary packages, generate the required JWT keys, configure the server-side auth files, and set up the client-side provider.
- “Configure Google OAuth for my Convex app.”
- The agent will follow the authentication workflow, specifically configuring the OAuth provider in the auth setup and ensuring all environment variables are correctly deployed.

Add sign-in to the app
Install and wire @convex-dev/auth for the current app: a provider (passkeys by default, or OAuth/password), the server config, the client hooks, and a sign-in UI — correctly, including the auth.config.ts that's the #1 real-world auth footgun.
Workflow
Install @convex-dev/auth (pinned build) and add it to convex.config.ts. With pnpm, also
pnpm add jose(it won't hoist otherwise); you need it for step 3.Add the provider in convex/auth.ts (Passkey by default; Password or OAuth like Google on request).
Generate the auth keys HEADLESSLY. Do NOT run the interactive
npx @convex-dev/authwizard: it needs a login/TTY and hangs in non-interactive, anonymous, or CI runs (the #1 auth time-sink). Generate JWT_PRIVATE_KEY + JWKS deterministically withjose: node -e 'import("jose").then(async({generateKeyPair,exportPKCS8,exportJWK})=>{const k=await generateKeyPair("RS256",{extractable:true});const priv=await exportPKCS8(k.privateKey);const pub=await exportJWK(k.publicKey);process.stdout.write(JSON.stringify({JWT_PRIVATE_KEY:priv.trimEnd().replace(/\n/g," "),JWKS:JSON.stringify({keys:[{use:"sig",...pub}]})}))})' > .auth-keys.json Then set JWT_PRIVATE_KEY and JWKS (from .auth-keys.json) plus SITE_URL on the deployment. Prefer the Convex MCPenvSettool, one call per var, to avoid shell-quoting the multi-line key. CLI fallback: use the NAME=VALUE form (npx convex env set "JWT_PRIVATE_KEY=$JWT"), NEVERenv set JWT_PRIVATE_KEY "$JWT"(the value starts with-----BEGINand the CLI parses the leading-as an unknown flag). SITE_URL is the dev URL (e.g. http://localhost:3000). Delete .auth-keys.json after.Write convex/auth.config.ts (the silently-always-signed-out bug lives here if it's wrong).
Wire the client: ConvexAuthProvider, the sign-in component, and route guards. If you import shadcn/ui primitives (button, input, textarea, label, and so on), add them first with
npx shadcn@latest add <name>; a missing @/components/ui/* is a hard build error.Verify a sign-in round-trips before declaring done.
Rules
Generate JWT_PRIVATE_KEY/JWKS with
jose(extractable RS256; PKCS8 newlines to spaces; JWKS = {keys:[{use:"sig", ...publicJwk}]}). Do NOT run the interactivenpx @convex-dev/authwizard: it hangs headless/anonymous. Set the vars via the MCPenvSettool or the NAME=VALUE CLI form.Always write auth.config.ts: a missing/incorrect one makes the app silently always-signed-out with no error.
Passkeys by default; only switch to password/OAuth on explicit request.
Install any shadcn/ui primitive you import up front (
npx shadcn@latest add ...); a missing @/components/ui/* is a hard build failure.Verify a real sign-in works before finishing.
