I tried that, but don’t remember my secret question. Help! Call our practice and we’d be happy to email you a direct link to reset your password. However, DVO cannot change your security questions or answers. Only patients can change their secret questions under their “My account” settings once logged into their portal account. I don’t have access to the email address I used when I set-up my portal account. Call our practice and we’d be happy to update your email address in Mosaiq and Medfusion, and assist you with your user ID and/or password reset. What are the requirements for my password? Your password must be at least 6 characters, must contain at least one number OR an upper case letter, and should not contain any special characters. I’ve been locked out because of too many password attempts. Please wait 15 minutes and try again. We set a maximum number to ensure the security of your account. What browser should I use? Internet Explorer, Mozilla Firefox, Chrome and Safari are all supported. Be sure you’re using a current version of your web browser for optimal performance.
