If you see an “Authentication failed” error when trying to log in to the ButterflyMX mobile app, the issue is often related to the date and time settings on your device.

For security reasons, the app relies on your device’s clock being accurate. If the time on your phone is incorrect or manually set, the authentication process may fail and prevent you from signing in.

Why This Happens

Authentication systems use timestamps to verify login requests. If your phone’s clock is out of sync with the network, the system may reject the login attempt and display the “Authentication failed” message.

This typically happens when:

• The device’s date or time is set manually

• The phone’s clock is not synchronized with the network

• The time zone is incorrect

How to Fix the Issue

Updating your phone’s date and time settings usually resolves the problem.

Follow these steps:

• Open your phone’s Settings

• Tap Date & Time

• Enable Set time automatically or Automatic date & time

• Make sure the correct time zone is selected

Once automatic time is enabled, try logging in to the ButterflyMX app again.

Additional Help

If the issue continues after updating your date and time settings, additional troubleshooting may be required.
