If you’ve already confirmed your username and password are correct, you may need to check your phone settings next. Login issues can be caused by having the incorrect country or region selected in your smartphone settings. Within smartphone settings, set the Region (iOS) and Language/Region (Android) to match your Dexcom account then, reinstall the Dexcom Clarity app and try again. Please contact Tech Support if you need further assistance.
