Microsoft Authenticator app not working: Possible fixes
Now that you have understood the possible causes of why the Microsoft Authenticator app is not working let us move to the fixes.
Fix your network
Make sure that there is no network issue at your end. For that, there are certain things that you must first take care of:
- First, ensure there isn’t any internet outage in your area. You can ask your Internet Service Provider for the information, or you can visit their website.
- If there is no outage, it is time to check the hardware to ensure they are not damaged. Check all the hardware associated with the internet connection. That includes your router, modem, power cable, and the main power source, among others. Ensure that all the hardware is undamaged and working properly. If you notice any damage, change it asap.
- If the hardware is fine, then it is time to check the connections. Make sure that the cables are secured firmly in the proper ports.
- Sometimes, there is too much distance between the WiFi and the receiving device. Make sure that the distance is less. Or, you can directly connect the internet to your computer as it provides a more stable speed than WiFi.
- Also, remove any other electronic appliances that might interfere with the WiFi signals. While at it, place the WiFi on a raised platform so that the devices catch signals seamlessly.
- If many devices are connected to your network, remove them before playing games on the internet, as the devices share the limited bandwidth of the plan. You can also think of upgrading your existing internet plan.
