When to Call a Professional
Contact Blizzard Support directly if your account remains locked after more than 24 hours, if you cannot access your registered email to reset your password, if you believe your account was hacked and items or characters have been altered, or if the Blizzard Authenticator is no longer accessible to you (e.g., lost phone). Blizzard's account recovery specialists can verify your identity through alternative methods and restore compromised accounts.Frequently Asked Questions
What does Battle.net error WOW51900118 mean?
Error WOW51900118 means your World of Warcraft account has been temporarily locked by Blizzard's security system. This usually happens after multiple failed login attempts, a login from an unusual location, a recent password change, or suspected unauthorized access. It is a protective measure designed to prevent someone from breaking into your account.
How long does the WOW51900118 account lock last?
In most cases, the temporary lock lifts automatically within 15 minutes to a few hours. If the lock was triggered by a security concern rather than just failed logins, you may need to verify your identity via email or contact Blizzard Support to have it removed manually. Repeatedly trying to log in while locked can extend the lockout duration.
Will I lose my WoW characters or progress because of this error?
No, error WOW51900118 is an account access lock, not a ban or suspension. Your characters, items, and progress are all safe. Once the lock is lifted and you regain access, everything will be exactly as you left it.
Can error WOW51900118 happen even if I entered my password correctly?
Yes. The lock can be triggered by factors beyond just wrong password attempts, such as logging in from a new device or location, a VPN or proxy that Blizzard's system does not recognize, or an automated security sweep flagging your account. Verifying your identity through your registered email usually resolves it quickly.
Does using a VPN cause WOW51900118?
Yes, using a VPN can trigger this error because Blizzard may detect the login as coming from an unusual or suspicious IP address. If you are using a VPN, try disabling it before launching Battle.net and logging into World of Warcraft. If the error goes away, your VPN's IP was likely flagged by Blizzard's security system.
