How do I log in? What can I do if I forgot my password? How do I change my password? What can others see about me? How can I change/edit my personal information? How can I close my account? Can I re-open a closed account? What are my usage limits per level? How can I level up/raise my limits? Is the level-up/raise my limits option for free? Where can I find the push notifications? Can I access my OKTO account from other devices? Can I change my country of residence?
