The Authenticator app is a popular tool for enhancing security with two-factor authentication. Sometimes, it may stop working properly on Windows 11 due to various reasons. This guide will help you fix common issues with the Authenticator app step-by-step.
Whether your app is not syncing codes, crashing, or failing to generate codes, these solutions cover simple to advanced fixes. Each step is explained clearly so you can follow along without confusion.
By following this guide, you will be able to identify the cause of the problem and get your Authenticator app running smoothly again. No technical expertise is required.
Let’s dive into some quick checks before moving on to detailed solutions.
Quick Note: Basic Checks Before You Start
- Check Internet Connection: The Authenticator app sometimes needs an active internet connection to sync time or accounts.
- Verify Date & Time: Incorrect date or time settings on your PC can cause the app to generate invalid codes.
- Restart Your PC: A simple restart often fixes temporary glitches causing the app to malfunction.
- Update Windows & App: Ensure that both Windows 11 and the Authenticator app are updated to the latest versions.
Step 1: Confirm Date and Time Settings
The Authenticator app relies heavily on the correct date and time to generate valid codes. If your system clock is off, codes will not be accepted by services.
- Click on the Start menu and select Settings.
- Go to Time & Language and then Date & time.
- Make sure Set time automatically is turned on.
- If it is on, try toggling it off and on again to force a resync.
- Also, set Set time zone automatically to on.
- Close settings and check if the Authenticator app works now.
Why this matters: The app uses time-based one-time passwords (TOTP), which depend on synchronized clocks. Even a few seconds of difference can invalidate codes.
Step 2: Check App Permissions and Background Access
Windows 11 may restrict apps from running in the background or accessing necessary permissions, which can affect the Authenticator app.
- Open Settings and go to Apps & features.
- Find the Authenticator app in the list and click the three dots next to it.
- Select Advanced options.
- Scroll down to Background apps permissions and ensure it is set to Always or Power optimized.
- Check that the app has permission to access the internet if required.
- Restart the app and test it again.
Why this matters: If the app cannot run in the background or access network resources, it may fail to sync or generate codes properly.
Step 3: Clear the App Cache and Data
Corrupt cache or stored data might cause the app to malfunction. Clearing these can often resolve unexpected errors.
- Go to Settings > Apps & features.
- Locate the Authenticator app and click the three dots, then choose Advanced options.
- Scroll down to find the Reset section.
- Click on Repair first – this will try to fix the app without deleting data.
- If the problem persists, click Reset. This will delete app data and restore it to default.
- Open the app again and reconfigure your accounts if needed.
Why this matters: Repairing keeps your data intact, while resetting removes any corrupted files that may be causing the issue.
Step 4: Reinstall the Authenticator App
If clearing the cache and resetting did not help, reinstalling the app is the next step.
- Open Settings > Apps & features.
- Find the Authenticator app, click the three dots, and select Uninstall.
- Confirm the uninstall process.
- Go to the Microsoft Store and search for your Authenticator app.
- Download and install the latest version.
- Open the app and set up your accounts again.
Why this matters: Reinstalling ensures you have a clean, updated version of the app without any corrupted files.
Alternative Method: Use an Authenticator Extension or Mobile App
If you continue to face problems on Windows 11, consider using the mobile version of the app or a trusted browser extension as a temporary solution.
- Install the Authenticator app on your smartphone (iOS or Android) and sync your accounts.
- Use browser extensions like Authy or others that support two-factor authentication.
These alternatives provide flexibility and reduce dependency on the Windows app specifically.
