My Account Details Screenshot 

View and edit your contact and insurance information on file with your provider via the My Account Details page. Once you click "Save," newly-added or edited information is shown in orange, pending review and acceptance of the new information by your provider.

Core information, like your name and date of birth, cannot be updated via the Patient Portal. Call or see your provider, or send a secure message, to update this or any other personal information that doesn't appear on the Account Details page.
