How to Fix a Microsoft Account Sign-In Loop on Windows

If Windows keeps bouncing you back to the Microsoft sign-in screen, you are likely dealing with a Microsoft account sign-in loop. It can stop apps from syncing, block OneDrive, and make your PC feel unusable. The good news is that this issue is often caused by a few fixable settings, cached credentials, or network problems. Below, you will learn how to work through the most effective fixes in a safe order.

Why this happens

A Microsoft account sign-in loop usually starts when Windows cannot complete the sign-in handshake and save it correctly. That can happen if your password was recently changed, two-step verification is waiting for approval, old credentials are stuck in Windows Credential Manager, or your date and time settings are incorrect.

It can also happen after a Windows update, when your internet connection is unstable, or if a work or school account conflicts with your personal Microsoft account. In some cases, security software or a corrupted profile setting interrupts the process and Windows keeps asking you to sign in again.

Fix it step by step

1. Confirm your Microsoft account works in a web browser. Open a browser and sign in at the official Microsoft account page. If you cannot sign in there, reset your password or complete any identity verification prompts first. If browser sign-in works, the problem is likely on the PC rather than with the account itself.
2. Check your internet connection and time settings. Make sure your PC is online and not connected through a flaky public network or VPN. Then go to Windows date and time settings and turn on automatic time and automatic time zone if available. Incorrect clock settings can prevent Microsoft services from authenticating properly.
3. Remove old saved credentials. Search for Credential Manager in Windows, open it, and look under Windows Credentials and Generic Credentials for Microsoft, Office, Outlook, OneDrive, or Xbox-related entries. Remove only the entries related to your Microsoft account or Microsoft apps, then restart the PC and try signing in again. This often fixes a Microsoft account sign-in loop caused by stale login tokens.
4. Disconnect and reconnect the Microsoft account. Go to Settings > Accounts and review your sign-in and email account sections. If your Microsoft account is listed but not syncing correctly, sign out of Microsoft apps, remove the affected account where appropriate, restart the computer, and add it back. If this is your main Windows sign-in account, avoid changing it blindly; instead switch to a local administrator account first if one is available.
5. Install pending Windows updates. Open Settings > Windows Update and install all important updates, then restart. Microsoft account and authentication bugs are sometimes corrected through cumulative updates. After the restart, try signing in again before opening multiple Microsoft apps at once.
6. Check for work or school account conflicts. In Settings > Accounts > Access work or school, look for old business or school accounts that are no longer used. Disconnect only accounts you recognize and no longer need. A stale organizational sign-in token can interfere with a personal account and trigger repeated login prompts.
7. Test with a clean app sign-in. Open one Microsoft app such as OneDrive or the Microsoft Store and sign in there first. If it signs in successfully, wait a minute for syncing to finish, then check the rest of the system. If all apps ask for sign-in at the same time, they can sometimes keep re-triggering the loop before Windows stores the token correctly.
8. Create a new Windows user profile if the issue remains. Add a new local administrator account or another test user profile, sign in to that profile, and then connect your Microsoft account there. If the new profile works normally, your original Windows profile may be corrupted. Move important files carefully before considering a full profile replacement.

If the problem keeps coming back

If your Microsoft account sign-in loop returns after updates, restarts, or password changes, the issue may be tied to profile corruption, a background sync app, or a security tool blocking authentication. At that point, it is worth checking Event Viewer, reviewing startup apps, and making sure your Microsoft account recovery information is current. If you do not want to risk changing account settings alone, professional remote support can save time and help prevent data loss.

Frequently asked questions

Why does Windows keep asking me to sign in to my Microsoft account?

This usually happens because Windows cannot save or validate your sign-in token. Common causes include outdated cached credentials, a recent password change, incorrect date and time settings, or a conflict with another connected account.

Will removing saved credentials delete my files?

No. Removing Microsoft-related entries from Credential Manager does not delete your personal files. It only removes stored sign-in information, so you may need to sign back in to apps like Outlook, OneDrive, or the Microsoft Store afterward.

Should I switch to a local account to stop the sign-in loop?

Sometimes a local account can help you troubleshoot, especially if the loop affects your main Windows profile. However, switching account types can change sync behavior for apps and settings, so it is best to do that carefully and only if simpler fixes have not worked.
