Hello!
I have a suggestion to the development team of the Online Family software.
It would be much easier if you could implement a voucher system for buying more time.
As it is now I need to be at the computer and log in (or give my id and password to my kids...) in order to give them more time on the computer.
I propose that you instead implement a system where I, via the Online Family app or webpage can create a code which will grant my kids usage for a certian time which I specify when I create the code.
I then can SMS, or give them the code in a voicecall and when they write this code instead of my email and password they have been granted the extra time.
