(CNN) -- Anyone who has signed up to enroll in Obamacare on Healthcare.gov is being told that their password must be reset.
'All passwords were deleted for existing accounts as part of the upgrade process,' a call center representative told CNN's Elizabeth Cohen Thursday morning. The representative said everyone must call in to reset their password; it cannot be done online.
Representatives can be reached at 1-800-318-2596.
The federal site has been plagued by technical glitches since Obamacare launched on October 1.
