This sign-in loop on Xbox app or Minecraft Launcher is commonly caused by stuck or corrupted cached sign-in credentials on the PC, especially when the account works in a browser or on another device.
Try these steps in order:
- Clear saved Microsoft/Xbox credentials
- Open Credential Manager.
- Go to Windows Credentials.
- Remove entries related to Microsoft account, Microsoft Store, and Xbox.
- Restart the PC.
- Try signing in again.
- Reset the affected app
- Open Settings > Apps > Apps & features.
- Find the app that is looping, such as Xbox app or Minecraft Launcher.
- Select Advanced options.
- Choose Reset.
- Then try signing in again.
- If the account itself may be blocked during verification
- Try another verification method connected to the account.
- Try a different network, such as switching between Wi‑Fi and mobile hotspot.
- If repeated attempts were made, wait at least 24 hours before trying again. Repeated retries can extend the block.
- Use the sign-in helper: Start
- If the username or password is no longer accepted even though it is correct
- Use Recover your account: Recover your account
- Make sure the sign-in address uses the correct domain, such as the correct Outlook, Hotmail, or Live domain.
- If one alias is not recognized, try another email alias or phone number on the account.
- If recovery still says the account cannot be found
- Contact support and report that the username has stopped working: Contact support
If the loop happens only inside Microsoft apps on this PC, step 1 is the most directly matched fix from similar cases.
