If you change your country, our system will request you to reconfirm your login before accessing your user profile. Change of IP address will also trigger some advanced validations, depending on your subnet/country.
In case someone tries to access your account with a wrong password, our system will lock your user account automatically. This lock will always be temporary and you can gain access to your account after a couple of security confirmations.
Your birthday is a special day for us. We celebrate it with you, and it works as a secret token that connects you and our system together. But do not add a wrong birthday, or change birthday time to time.
