In the country where I live we have a system which allows me to prove my identity online without having to show my ID (actually I must admit I'm quite impressed by this system). But sadly, Wise is not taking advantage of that..
There is an initiative (mandatory, for all member states!) to make these interoperable, which will hopefully make them more useful for applications like this.
login.gov is unfortunately only accepted by government services, and as far as I can tell only federal ones too – at least NY state has their own thing... (NY.GOV ID)
