Signed in to X3 Konto, Growth Intelligence asks for the password again

Area: Account and access · Updated: 1 Nov 2026 · Auf Deutsch · All articles

Symptoms

  • You signed in on the X3 Konto page (from a bookmark or after signing out of the Sales Engine) and landed on „Willkommen zurück.“ of Growth Intelligence right away.
  • A saved link to a Growth Intelligence page that pointed at the X3 Konto address asked for the password, although X3 Konto showed you signed in.

Cause

  • X3 Konto and Growth Intelligence live on two addresses with separate sign-ins in the browser; X3 Konto hands its sign-in over with a one-time code.
  • Before the update of 1 Nov 2026 a sign-in on X3 Konto without a destination continued into Growth Intelligence directly, and links of Growth Intelligence on the X3 Konto address skipped the hand-over.

How to fix it

1. Sign in on X3 Konto

  • In the dashboard: accounts.x3growth.io › Bei X3 anmelden
  • With Claude (MCP): No MCP tool (signing in needs the person's password in the browser)
  • Since the update of 1 Nov 2026.

Without a destination the sign-in opens X3 Konto › Profil (https://accounts.x3growth.io/account/profile). With a destination (for example from the Sales Engine) it continues there.

2. Open Growth Intelligence from there

  • In the dashboard: X3 Konto › Produkt wechseln › Growth Intelligence
  • With Claude (MCP): No MCP tool (the hand-over of the sign-in runs only in the person's own browser (one-time code, 60 seconds))

Any Growth Intelligence page opened on the X3 Konto address, such as an old bookmark, goes through the same hand-over: no second password.

3. Still asked? Sign in once on Growth Intelligence

  • In the dashboard: Growth Intelligence › Anmelden
  • With Claude (MCP): No MCP tool (the browser blocked the hand-over (cookies off for one of the two addresses, private window closed in between))

Allow cookies for both X3 addresses. Signing out in either place ends both sign-ins.

How to tell it worked

  • Growth Intelligence opens signed in after the sign-in on X3 Konto, without its sign-in page on the way.

Growth Intelligence and X3 Konto keep one sign-in per browser. When X3 Konto knows you and Growth Intelligence does not yet, X3 Konto hands the sign-in over with a one-time code that only works in the same browser.
