You must have an account with Google in order to register with Den4Dogs. That way you can be sure we don't store any critical information about your login credentials. Google are experts in handing data security and you can be sure your password is not hacked. That's why we let Google handle this information. Many people already have a Google Account but in case you need to create one it's quite easy and fast to set up. In addition Google lets you use 2 Factor Authentication on your account, which is something we would strongly recommend for all your internet accounts - Gmail, Facebook and others. In the future we will add Facebook login as well, but not for the time being unfortunately.
