Ask HN: Is binance smartphone application not safe?

So, I just logged in the binance android application and contacted support, upon requesting they asked me for security reasons to provide a selfie, they could see I was logged in, but they asked me to provide a selfie holding a document in hand, for the previous mentioned security reasons, but I could move money from the app without friction, so is the binance android app secure or that's an admission that the app might have security issues in proving the identity of who is using it? Has it ever happened to you that being logged in with 2FA was not considered secure?
