  AADSTS50058: A silent sign-in request was sent but no user is signed in. The cookies used to represent the user's session were not sent in the request to Microsoft Entra ID. This can happen if the user is using Internet Explorer or Edge, and the web app sending the silent sign-in request is in different IE security zone than the Microsoft Entra endpoint (login.microsoftonline.com).

Resolution

Try the following steps to resolve the issue:

1. Enable third-party cookies and local data in your browser or app.

2. Clear your browser's cache and cookies and try again. Cached data can sometimes prevent you from signing in.

3. Try signing in with a different browser. For a list of supported browsers, see system requirements.

4. Check your network connection to make sure it's stable.

5. If you're getting Microsoft Entra errors, they're usually related to user authentication and authorization. The error page might contain additional information that can help diagnose and fix the problem. To resolve Microsoft Entra errors, you might need assistance from your IT department.

6. Check the "Third-party Storage Partitioning" setting in your browser to make sure it's disabled.

   Note

   Consider this resolution step only when you experience sign-in or sign-out issues under one of the following conditions:

   • You use a device that has multiple Microsoft Entra identity sign-ins to access different applications.
   • You access multiple applications using Microsoft Entra across more than one tab. When you sign out of one tab, you observe that you aren't signed out of the second tab.
   • You access Power Apps that are embedded via an iframe in a third-party website.
   • You access a canvas app that's embedded in a model-driven app form.

Check the "Third-party Storage Partitioning" setting in Microsoft Edge or Google Chrome

• In Microsoft Edge, you can check the setting by navigating to edge://flags/#third-party-storage-partitioning using the address bar.
• In Google Chrome, you can check the setting by navigating to chrome://flags/#third-party-storage-partitioning using the address bar.

Enable storage of third-party cookies and local data in your browser or app

Power Apps stores some data locally, such as user identity and preferences, using your browser's capabilities. Problems occur if the browser blocks the storage of such local data, or third-party cookies set by Power Apps.

Most browsers allow settings to reflect the changes immediately. You might also need to close all the browser windows and reopen them instead.

To enable this setting for the Power Apps and Dynamics 365 mobile apps for iOS, you need to work through the iOS settings linked to the app rather than through the browser settings for iOS.

These instructions are shown on the following tabs.

Microsoft Edge

• Option 1: Enable storage of third-party cookies and local data for all sites

  1. Select Settings > Cookies and site permissions.
  2. Expand Cookies and data stored.
  3. Ensure the Block third-party cookies setting is disabled.
  4. If present, remove the following sites from the site-specific cookie configuration under Block and Clear on exit:
     • https://create.powerapps.com
     • https://*.create.powerapps.com
     • https://make.*.powerapps.com
     • https://make.powerapps.com

To allow apps to use cookies when they're embedded in another client, such as SharePoint, follow these steps:

1. Navigate to Settings and select Privacy & security.
2. Look for Enhanced Tracking Protection and select Manage Exceptions.
3. Add the URL of the website where the apps are embedded. For example, if the apps are embedded in SharePoint, you need to add the SharePoint URL to the exceptions list. This will allow the embedded apps to use cookies.

Clear your browser cache

The browser cache is stored on your device's hard drive. When you visit a website, your browser downloads certain information that allows it to load faster when you revisit the same website in the future. Some Power Apps features use the browser cache to provide a faster user experience. In some cases, you might want to clear your browser cache. Here are the instructions for different browsers:

• Microsoft Edge
• Google Chrome
• Safari on Mac
