How to Fix “Can’t Sign In to Microsoft Account” on Windows 11

Fix: Can’t Sign In to Your Microsoft Account on Windows 11

If you’re locked out of your Microsoft account on Windows 11, don’t panic — there are several ways to fix it. The issue might be caused by a forgotten password, network problems, corrupted system files, or damaged credentials. In this step-by-step guide, you’ll learn how to reset your password, repair Windows files, clear old credentials, and even create a new admin account if needed.

🔑 Step 1: Reset Your Microsoft Account Password

If you can’t log in, start by resetting your Microsoft account password.

1. On the login screen, click “I forgot my password.”
2. Choose how you’d like to verify your identity (email, SMS, or Authenticator app).
3. Enter the verification code Microsoft sends you.
4. Set a new password and try signing in again.

If that doesn’t work, you can also reset your password from another device:
👉 Go to https://account.live.com/password/reset

Tip: Make sure the PC is connected to the internet so the new password syncs properly with your local system.

🌐 Step 2: Check Your Internet Connection

Microsoft accounts need an active connection to verify your credentials. If your network is unstable, you might see “We can’t sign in to your account” or “Something went wrong.”

Try these steps:

• Restart your router or modem.
• Switch from Wi-Fi to Ethernet (if available).
• Try a mobile hotspot to rule out ISP issues.

If you still can’t connect, boot into Safe Mode with Networking:

1. On the login screen, hold Shift and click Restart.
2. Go to Troubleshoot → Advanced options → Startup Settings → Restart.
3. Press F5 for Safe Mode with Networking.

Then open:
Settings → System → Troubleshoot → Other troubleshooters → Network Adapter → Run.

This runs the Windows Network Troubleshooter to automatically repair connection problems.

⚙️ Step 3: Repair Windows System Files

If you recently installed an update or driver and now can’t log in, system files might be damaged. You can fix this using SFC (System File Checker) and DISM (Deployment Image Servicing and Management).

1. Boot into Safe Mode with Command Prompt.
2. Type these commands, pressing Enter after each:
3. sfc /scannow

Wait until it completes, then run:

DISM /Online /Cleanup-Image /RestoreHealth

1. If Windows certificates are broken, restart the Cryptographic service:
2. net stop cryptsvc
3. net start cryptsvc
4. Restart your PC and try logging in again.

Note: If SFC says it found but couldn’t fix files, run the command again — sometimes it takes multiple passes to repair everything.

🧾 Step 4: Clear Corrupted Credentials

If Windows keeps rejecting your correct password, the saved credentials might be corrupted.

1. Boot into Safe Mode.
2. Open File Explorer and go to:
3. C:\Users\[YourUsername]\AppData\Local\Microsoft\
4. Find the Credentials folder and rename it to Credentials.old.
   You can do this from Command Prompt too:
5. ren “C:\Users\[YourUsername]\AppData\Local\Microsoft\Credentials” “Credentials.old”
6. Restart your computer — Windows will create a fresh credentials folder automatically.

This step clears cached login data that could be blocking your account.

👤 Step 5: Create a New Local Admin Account

If you’re still stuck, create a new admin account from the Recovery Environment so you can sign in and recover your data.

1. On the login screen, click Power → Restart while holding Shift.
2. Choose Troubleshoot → Advanced options → Command Prompt.
3. Type the following commands and press Enter after each:
4. net user /add TempAdmin *P@ssw0rd!
5. net localgroup administrators TempAdmin /add
6. Close Command Prompt and restart your PC.
7. On the sign-in screen, log in using the TempAdmin account.

If this works, you can back up your files from your old profile and use this new one as your main account.

🧹 Step 6: Reset Windows Without Losing Files

If none of the above works, you might need to reset Windows 11.

1. On the login screen, hold Shift and click Restart.
2. Go to Troubleshoot → Reset this PC.
3. Choose Keep my files → Cloud download.

This reinstalls Windows while keeping your personal files intact. You’ll need to reinstall apps, but it often resolves login-related corruption.

If you can’t reach this screen, use a Windows 11 installation USB:

• Boot from it → Repair your computer → Troubleshoot → Reset this PC.

🧠 Step 7: Verify Windows Settings and Updates

Once you regain access, check the following to prevent future sign-in issues:

• Windows Updates: Go to Settings → Windows Update → Check for updates.
• Date and Time: Ensure Set time automatically and Set time zone automatically are both turned on.
• Network sync: If you use multiple devices, verify your account at https://account.microsoft.com.

Also, re-add your Microsoft account to Settings → Accounts → Email & accounts to sync credentials again.

💡 Bonus Tip: If PIN or Windows Hello Fails

If your password works but PIN or facial recognition fails:

1. On the login screen, click I forgot my PIN.
2. Follow the steps to remove and reconfigure Windows Hello.
3. Once signed in, set up a new PIN under Settings → Accounts → Sign-in options.
