Quick answer: Sign out of the Minecraft Launcher and sign back into the correct Microsoft account, then set Windows time and time zone automatically and press Sync now. Restart the launcher. If the message remains, check Xbox service status and repair Store/Xbox components before changing DNS.
Before you start
- Confirm which Microsoft account owns Minecraft or has the active Game Pass entitlement.
- Close Minecraft and the launcher completely.
- Do not share verification codes, recovery codes or passwords with anyone.
Fix the authentication error on Windows
- Check service status. Review Xbox status for account, profile and multiplayer incidents. A live sign-in outage cannot be fixed by reinstalling Minecraft.
- Sign out and back in. In the Minecraft Launcher, open the profile menu, sign out, close the launcher, reopen it and sign in with the Microsoft account that owns the game.
- Match Store and Xbox accounts. Open Microsoft Store and the Xbox app and confirm they use the intended account. A mismatched Store entitlement and Xbox profile can cause confusing license or multiplayer prompts.
- Synchronize date and time. Open Settings > Time & language > Date & time. Enable automatic time and time zone where available, then select Sync now. Restart the launcher.
- Install app updates. In Microsoft Store, open Library > Get updates. Update Minecraft Launcher, Xbox and Gaming Services, then restart Windows.
- Repair the launcher and Xbox components. In Settings > Apps > Installed apps, use Advanced options > Repair for the launcher and Xbox app. Test before using Reset.
- Refresh networking. Restart the router and PC. If only name resolution fails, flush the Windows DNS cache with
ipconfig /flushdns. - Optional DNS test. The video demonstrates Cloudflare DNS (
1.1.1.1/1.0.0.1). This is an unofficial, reversible network test. Record the current adapter setting and restore automatic DNS if it does not help.
Why correct time matters
Microsoft sign-in uses time-limited security tokens. A substantially incorrect device clock can make a valid token appear expired or not yet valid. Synchronizing time does not bypass account security; it lets the PC validate tokens against the correct time.
Other platforms
On console or mobile, start with the game’s Microsoft-account sign-out/sign-in flow, system date and time, game updates and Xbox status. Do not follow Windows adapter menus on Switch, PlayStation, Xbox, Android or iOS. Account linking rules vary by platform; contact Minecraft Support if the wrong Microsoft account was linked.
Warnings
Do not create repeated new accounts to work around a lost entitlement, and never remove account security. A DNS change does not repair a suspended account, parental restriction or expired Realms subscription.
Frequently asked questions
Will signing out delete my worlds?
Signing out should not delete local worlds, but keep normal backups before app resets or reinstalls.
Why does Sync now help?
Authentication tokens depend on an accurate clock. A stale or incorrect time can break validation.
What if it fails only on one server?
The server may be offline, incompatible or blocking the account. Test an official server or Realm and check the server owner’s status.
