Why do people keep thinking the government will waste their time trying to crack your password ?
They don't waste their time like that, what they do is issue a warrant to whomever holds your information (google, apple, MS , whomever) to release it to them.
Just look at the backlog of iphones the US gov has that it cannot unlock, unless it is some high profile case they don't waste their time or money with that shit.
The US government has taken people to black sites around the world and has tortured people to give up information, why would they place nice with you ?
