desktop_signup_deprecated

Error message

Create your account in the browser to choose a secure password.

What it means

signUpEmail is intentionally unsupported: desktop email/password signup was deprecated in favor of the browser-based Den signup flow (which provides password-strength feedback and invite handling). Any call throws a 410 Gone DenApiError with code "desktop_signup_deprecated". The parameters are ignored.

Solutions

Replace signUpEmail calls with opening buildDenAuthUrl(baseUrl, "sign-up") in the browser
Route the user through the browser signup and complete sign-in via the desktop handoff flow
Remove dead signup UI from the desktop app

Example fix

// before
await client.auth.signUpEmail(email, password);
// after
openExternal(buildDenAuthUrl(baseUrl, "sign-up"));
const result = await exchangeHandoffAndSignIn(grant, { baseUrl });

Defensive patterns

Strategy: validation

Validate before calling

const supportsDesktopSignup = false; // deprecated upstream
if (wantsSignUp) openExternal(buildDenAuthUrl(baseUrl, "sign-up"));

Try / catch

try {
  await client.auth.signUpEmail(email, password);
} catch (err) {
  if (err instanceof DenApiError && err.code === "desktop_signup_deprecated") {
    openExternal(buildDenAuthUrl(baseUrl, "sign-up"));
  } else throw err;
}

Prevention

Never call signUpEmail; it always throws 410
Direct users to the browser signup via buildDenAuthUrl(baseUrl, "sign-up")
Complete sign-in through the desktop handoff flow after browser signup
Remove legacy signup UI from desktop surfaces

When it happens

Trigger: Calling client.auth.signUpEmail(email, password) directly from the desktop app.

Common situations: Old code paths or custom scripts written before the deprecation that attempted in-app account creation.
