Getting incorrect codes isn’t an uncommon issue in Google Authenticator. Fortunately, resolving the issue isn’t complicated. Before moving on to the steps, confirm you entered the correct code before it expired. You should also ensure the time on your device matches your time zone. If you’re still getting a notification that your code is incorrect, you can try syncing your device: 1. Launch the Google Authenticator app and press the three dots. 2. Choose “Time correction for codes.” 3. Press “Sync now.”
