There is some confusion on this front. Apparently Miranda gave them either the keys to the encrypted devices, the passwords to his online accounts or both.

It should be possible to clear this up but I can't find a direct quote of either Miranda or Greenwald on the matter.

It seems unlikely he had the keys to the files, he says he did not know what was there and it would make no sense to give the keys until he arrived.
