Which in it self is an offence. https://www.saunders.co.uk/news/prosecuted-for-your-password/
What you mean as in government asking for your password and you telling them you can’t give it up. OFC it applies. The problem is the impetus from government to enforce the law.
I meant as in it’s an inquiry not a criminal case, so wasn’t sure how much they could compel someone to release it. If the law is applicable though then yeah it’s not a good look for the government not to be seen to enforce it.
