Security – Planet DDS

I am a Denticon User or Admin locked out of my account by mistake. How can I recover my account without signing in?
I received an error message that a Data Breach on an app or site exposed my password and Chrome recommended that I change my Denticon password. What does this mean and what should I do?
How does Denticon protect my data?
What cyber security protocol does Planet DDS use in order to prevent hacking of its software products?
