Enabling the Authenticator is simple. After downloading and installing the free mobile app, open your account settings to activate and link it.

You can choose to receive verification codes via SMS text messages or via push notifications in the app itself. With everything linked, you’ll now receive time-sensitive codes to enter at login. As long as your phone is in your possession, even someone with your account password wouldn’t be able to access your account.

Workarounds to Fix Battle Net Authenticator Not Sending Code Issue

Despite its effectiveness at bolstering security, many users occasionally encounter issues with the Authenticator failing to deliver verification codes. This prevents accessing your gaming profile and characters when codes are needed but aren’t received. But before sounding the alarm, there are several troubleshooting steps you can try to get the Authenticator working again:

Check Internet Connection

As is an online gaming platform, a stable internet connection forms the crux for vital services like the Authenticator to work properly. Connectivity issues could prevent your phone from communicating with servers to coordinate verification codes.

First, try rebooting your modem and router to reestablish a clean, consistent connection. Disable any VPN services temporarily as they can sometimes interfere with traffic. Toggle airplane mode on and off on your phone to renew the cellular data signal. Run a speed test to check if connectivity levels return to normal.


Like most software, could experience occasional hiccups that prevent certain components from delivering their intended functions. The core application failing to convey authentication requests represents one such possibility.

Attempt fully closing out of the desktop app and smartphone mobile app via your device’s task manager. Then launch again to essentially “reboot” the platform. While at it, check for any pending updates which could harbor bug fixes related to the Authenticator system.

Verify Time and Date Settings

Odd as it may seem, incorrect time and date settings can definitely interfere with time-sensitive services – like the Authenticator which generates fresh codes every 30 seconds.

Double check that your computer’s date, time zone, and AM/PM settings show the current accurate information. Enable the “Set time automatically” and “Set time zone automatically” options under Date & Time settings to continually sync those elements with internet atomic clock servers. Doing so guarantees temporal accuracy for authentication purposes.

Verify Phone Number and Notification Settings

The most obvious culprit for codes not getting delivered resides with the linked phone number itself. Start by ensuring your current active phone number properly appears under the Authenticator setup in your account settings.

While there, double check notification permissions, verifying that push notifications or SMS options show as activated for the Authenticator. Toggle them off and on if needed to re-register communication channels. Finally, confirm your phone has cellular signal and can receive texts/notifications from other apps.

Try Using a Different Phone Number

If you’ve triple checked settings to no avail, introduce a new phone number as a control variable. Temporarily link the Authenticator to another mobile device like a friend or family member’s phone.

Attempt logging into requesting a verification code. Check if the Authenticator promptly delivers the one-time password to the newly linked phone. If so, then some obstruction with your original number prevented code delivery.

Contact Support

Following the troubleshooting steps above should successfully revive a dormant Authenticator in most situations. However if your verification codes still don’t send after exhausting self-fixes, directly contacting Blizzard Support marks the wise next course of action.

Start by checking the support site for the Authenticator issue, which may offer additional specialized advice. Submit a detailed support ticket explaining when the problems emerged, steps attempted already, and relevant account/device details so representatives can better assist. Also explore support phone lines to speak with experts directly regarding your case.


Although’s Authenticator greatly enhances gaming security, it sometimes fails to send crucial verification codes promptly. Before hitting the panic button, try these calm troubleshooting steps to revive code transmission systematically. Restart your hardware, review account settings, add test numbers, and keep an eye on notification channels to uncover fixable issues. If authentication problems persist, seeking help from Blizzard’s support teams provides the best shot at a permanent fix.
