How do I log into Dexcom CLARITY?

Last Updated · September 28, 2021

You must have a Dexcom account to use Dexcom CLARITY. You must use the same Dexcom account for all your Dexcom devices. Do not create a duplicate Dexcom account or your data will not be found. If you are unsure if you have an account, try to recover the login. You already have a Dexcom account if you:

  • Use the Dexcom CGM app
  • Upload your Dexcom receiver to Dexcom CLARITY at home
  • Order supplies directly from Dexcom

You can reset your Dexcom username and password if needed. Please do not create a second Dexcom account.
