Many of the cases involving court-ordered access to personal devices include arguments centering on an individual’s right under the Fifth Amendment against self-incrimination, and about whether they can be compelled to reveal passwords or decrypt those devices.

In the Philadelphia case, for example, the officer was told to type in the passwords in a private room in the district attorney’s office, rather than to simply tell the password, which could be construed as testifying against himself.
