Can not login to portal.startups.microsoft.com or Foundershub

Hello,

we are experiencing issues logging into either the Startups Portal or Founders Hub.

We successfully opened an Azure subscription through the Startups Portal and were awarded the $1,000 credits. However, we are now stuck and unable to proceed with the next steps.

We are also unable to open a support ticket through either the Startups Portal or Founders Hub because we cannot log in.

When attempting to log in, we get stuck in a login loop: the system accepts our credentials, shows a loading page, and then redirects us back to the login page without displaying any error message.

Please help us regain access to the portal/hub or link a new account to our existing subscription. Any information on how to open a support ticket without being able to log in would also be greatly appreciated.

Best regards,

Konrad Mach

    Here's the complete solutions for the Founders Hub / Startups Portal login loop issue:

    1. Quick Fixes - Try These First

    Fix 1: Incognito + Different Browser

    Login loops are often caused by cached cookies/tokens.

    1. Open Chrome Incognito Ctrl+Shift+N
    2. Go to https://foundershub.startups.microsoft.com
    3. Try Edge or Firefox if Chrome fails. Safari has known issues with AAD.

    Fix 2: Bypass Founders Hub - Use Azure Portal Directly

    Since your subscription is already created:

    1. Go to https://portal.azure.com
    2. Log in with the same email
    3. Check Subscriptions - your $1,000 credits should be visible there
    4. You can create resources directly from here without Founders Hub

    Fix 3: Check Tenant / Directory

    Multiple tenants cause loops.

    1. In Azure Portal, click your profile icon top-right
    2. Click Switch directory
    3. Select the tenant where your subscription exists. Usually it's named "Default Directory" or your company name
    4. How to Open Support Ticket Without Login

    You have 3 options:

    Option 1: Azure Support - No Login Required

    1. Go to https://azure.microsoft.com/support/create-ticket/
    2. Select Technical > Subscription management > My issue is not listed
    3. Choose I can't access my subscription
    4. You can submit as guest without logging in

    Option 2: Direct Email

    Send email to: startups@microsoft.com or mfsupport@microsoft.com

    Subject: Login Loop - Founders Hub - Cannot Access Credits

    Include: Screenshot, your email, subscription ID if you have it from welcome email

    Option 3: Twitter/X

    Tweet to @MicrosoftStartups with the issue. They respond to login issues within 24hrs.

    1. Root Cause & Permanent Fix

    Common Cause How to Check Fix

    Guest User in AAD Azure Portal > Entra ID > Users > Check User Type Ask admin to convert Guest → Member

    Wrong Tenant Check tenant name top-right in portal Switch to correct directory

    MFA Loop No authenticator prompt shows Reset MFA at https://aka.ms/mfasetup

    Personal vs Work Account Email is @gmail/@outlook Use work email or add it as admin on subscription

    1. Save Your Credits - Do This Now

    To prevent $1,000 credits from expiring:

    1. If Azure Portal works: Start using it directly. Create resources from there.
    2. Add co-admin: Azure Portal > Subscriptions > Your Sub > Access Control (IAM) > Add > Owner > Add teammate's email. This gives backup access.
    3. Use Azure CLI: az login in terminal often works when browser fails. Then az account show to confirm access.

    Find Subscription ID without login: Check the "Welcome to Microsoft for Startups" email. It contains Subscription ID and Tenant ID. Give these to support.

    1. Template to Send Support

    Copy this and fill details:

    Issue: Login loop on Founders Hub / Startups Portal

    Account Email: ******@email.com

    Subscription ID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

    Tenant ID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

    Browser Tried: Chrome 126 Incognito, Edge

    Error: No error message. Redirects to login after credentials

    Impact: Cannot access $1,000 Azure credits. Cannot create support ticket

    Request: Please reset account access or link subscription to new email

    Key Points

    1. Your credits are safe - subscription exists even if portal is blocked
    2. Use http://portal.azure.com - 90% of work can be done there without Founders Hub
    3. Support responds fastest via email - mfsupport@microsoft.com

    This usually gets resolved in 1-2 business days. If not fixed in 48hrs, reply here and I'll give you the escalation path to PG team.

    Were you able to log into portal.azure.com at least?
