Frequently Asked Questions

Why does Minecraft say failed to login when I have the correct password?
This usually indicates server-side authentication issues with Mojang/Microsoft servers, internet connectivity problems, or corrupted launcher cache files. Follow the troubleshooting steps starting with checking server status and clearing launcher cache.
How do I fix Minecraft authentication servers are down error?
Check the official Minecraft status page to confirm if authentication servers are experiencing issues. If servers are down, wait for Mojang to resolve the problem. If servers are operational, restart your internet connection and Minecraft launcher.
Can firewall block Minecraft login?
Yes, Windows Firewall or third-party antivirus software can block Minecraft's connection to authentication servers. Temporarily disable these programs to test, then add Minecraft as an exception if it resolves the issue.
What should I do if my Minecraft account was migrated to Microsoft?
Use your Microsoft account credentials instead of your old Mojang account details. Download the latest Minecraft launcher and log in with your Microsoft email and password. Old Mojang account credentials will no longer work.
How long do Minecraft server outages usually last?
Minecraft server outages typically last 1-4 hours for planned maintenance and can vary for unexpected issues. Check official Minecraft social media accounts or status pages for updates on server restoration times.
