Hi there is not possable to have the option to have the password as button sequince in the PS App
Like to login you choose your profile and Press the X - X - O - (triangle) so this would be the password for this profile. and possable to choose other combination for others.
With Regards
unfortunately not, since passwords are attached to your user account, so you would be using the same password if you tried to use the web interface, so we can’t really use platform specific keys for password.
Is no way for you to use this kind of login like PS4 is using each button represent different number, like this image shows http://askabouttech.com/wp-content/uploads/2013/11/ps4-parental-control-enter-password.jpg
