Learn How to fix Battle.net authenticator not sending code and regain seamless access to your account, with our comprehensive troubleshooting guide.



The Battle.net authenticator is an essential security measure designed to protect your account from unauthorized access. It adds an extra layer of security by requiring a unique code in addition to your password when logging in. However, if you're facing issues with not receiving the code, it can be frustrating and leave your account vulnerable. But don't worry! In this blog post, we've got you covered with some friendly and effective workarounds to get you back on track.

 How to Fix Battle.net Authenticator Not Sending Code


 Check your internet connection



One of the first things you should do when facing issues with the Battle.net authenticator not sending codes is to check your internet connection. A stable and reliable internet connection is crucial for the authentication process. Here are a few steps you can follow:


  • 1. Restart your modem and router: Sometimes, a simple restart can fix connectivity issues. Power off your modem and router, wait for a few seconds, and then power them back on. This will establish a fresh connection and may resolve the issue.
  • 2. Ensure a stable internet connection is established: Check if other devices in your network can connect to the internet without any problems. If they can, then the issue may be specific to your computer or device. If not, you may need to contact your internet service provider for assistance.

If checking your internet connection doesn't solve the issue, the next step is to restart the Battle.net application. Here's what you can do:


  • 1. Close and relaunch the app: Close the Battle.net application completely and then relaunch it. This will ensure that you are using the latest version of the app and may resolve any temporary glitches or bugs.
  • 2. Consider reinstalling the application: If the problem persists even after restarting the app, you may want to consider reinstalling it. Uninstall the Battle.net application from your computer, download the latest version from the official website, and install it again. This will ensure a fresh installation and may fix any underlying issues.

Verify device's date and time


Sometimes, authentication code delivery issues can occur due to inaccurate date and time settings on your device. Here's what you can do to verify and correct them:


  • 1. Enable Auto Time and Date settings in Windows Settings: If you're using a Windows computer, go to the Settings menu and navigate to the Date & Time section. Ensure that the "Set time automatically" and "Set time zone automatically" options are enabled. This will ensure that your device's date and time are synchronized with the correct values.
  • 2. Ensure accurate time synchronization to prevent code delivery issues: If you're using a different operating system or device, make sure that the date and time settings are accurate. Inaccurate time settings can cause authentication code delivery delays or failures.

 Double-check your phone number


If you're still not receiving authentication codes, it's important to double-check your phone number settings. Here's what you can do:


  • 1. Review the phone notification settings in Account Settings: Log in to your Battle.net account and navigate to the Account Settings. Look for the phone notification settings and ensure that they are enabled. Sometimes, these settings can get accidentally disabled, preventing you from receiving authentication codes.
  • 2. Ensure that phone notifications are enabled to receive messages: Additionally, make sure that your phone's notification settings allow messages from the Battle.net app. Check if the app has the necessary permissions to send notifications and access your SMS inbox. If not, adjust the settings accordingly.

Try using a different phone number


If the issue persists even after double-checking your phone number settings, it may be worth trying to use a different phone number. Here's what you can do:


  • 1. Attempt entering an alternate phone number: In the Battle.net Account Settings, try entering a different phone number as your primary contact number. This will help you determine if the problem is specific to your current phone number or a broader issue.
  • 2. Verify if the code is being sent successfully to the new number: If you receive the authentication code on the new phone number, it indicates that the issue is related to your previous phone number. You may need to contact your mobile service provider to resolve any issues with receiving SMS messages.

 Contact support


If all else fails, don't hesitate to reach out to Battle.net support for assistance. Here's what you can do:


  • 1. Reach out to Battle.net support: Visit the Battle.net support page and look for the appropriate contact information. Explain your issue clearly and provide all the necessary details, such as your account information, device details, and the steps you have already taken to resolve the issue.
  • 2. Be patient and cooperative: Support teams are there to help you, but it may take some time to investigate and resolve the issue. Be patient and cooperative throughout the process, providing any additional information or following their instructions to the best of your ability.
