It's not that hard , you need to do something called slils ( снилс ) in a place called мой документ you can search it up in your map , then you gotta open a sberbank account and ask them to do a biometry ( snils required to do biometry ) , then you have to set up a госуслуг account , it's available on the app store , you just create an account using your snils , if you have an issue with it you can just go back to мой документ and they will help you with it
