How to Fix Continuous ‘Sign-In Required’ Popup on Windows?

If the “Sign-in Required” popup keeps appearing even though Windows shows that your account is already connected, it indicates a disruption in the connection between your device and your organization-associated account. This popup is triggered when Windows or an application tries to access the account but fails because the system no longer has proper access.

This issue often arises due to outdated credentials or changes in account permissions set by the organization. Now that we’ve identified the potential causes, let’s explore the solutions to resolve this problem.

1. Sign in to your Work or School Account

The simplest and most effective way to stop the “Sign-in Required” popup is to reconnect your work or school account after disconnecting it from the system. Even though the account appears to be connected, the popup persists due to a miscommunication between the device and the account. This occurs when Windows or an application attempts to access the account but fails because the connection is no longer valid. By signing in again, you can renew the connection and resolve the issue.

1. Press Win + I to open the Settings app.
2. Navigate to Accounts > Access work or school.
3. If your account is listed, select Manage your account and sign in to refresh the connection.
4. Alternatively, click Disconnect to remove the account, then select Connect to sign in again and renew the connection.

2. Disconnect the Work or School Account

If your account is linked to an organization but you no longer need it—especially if you’ve purchased a used system or left the organization—you can simply disconnect the account from your device settings. Once removed, the “Sign-in Required” popup will no longer appear.

1. Right-click the Start Menu and select Settings.
2. Navigate to Accounts > Access work or school.
3. If your account is listed, click Disconnect.
4. This should resolve the Sign-in Required issue.

3. Clear Stored Credentials in Credential Manager

If your work or school account credentials are outdated, corrupted, or no longer valid, Windows may fail to authenticate the account properly, triggering the “Sign-in Required” popup repeatedly. Clearing these stored credentials allows Windows to request fresh authentication data, which can resolve the issue.

1. Open Windows Search, type Credential Manager, and select it from the results. Credential Manager stores login details for various accounts, and outdated or corrupted credentials here can cause the “Sign-in Required” popup.
2. Select Windows Credentials. This section contains credentials for work or school accounts, Microsoft services, and other applications.
3. Locate entries related to your Work or School Account, Office 365, Azure AD, or Intune. These are often the culprits behind the “Sign-in Required” issue.
4. Select each relevant credential and click Remove. Deleting these credentials ensures that Windows will request fresh authentication data the next time you sign in.
5. Click Yes to confirm the deletion. This step ensures that outdated or corrupted credentials are completely removed from the system.
6. Restart your computer, then go to Settings > Accounts > Access work or school and sign in again. This allows Windows to re-establish a proper connection with your account.

If the issue persists after trying the above solutions, it’s recommended to contact your organization’s IT department. They can verify the Azure AD device registration status and ensure your device complies with the company’s policies. If everything checks out but the problem still isn’t resolved, consider reaching out to Microsoft Support for further assistance.
