In the US, use passwords to protect your phone. Passwords have been held by courts to be testimony and thus protected by the 5th Amendment. Patterns, swipes, facial recognition and fingerprints have been held by courts to be the equivalent of "keys" and you can be required to turn them over upon being ordered by a lawful authority (such as a police officer demanding them). Passwords require a court order and if you have a competent attorney, they can argue that revealing the password would result in self-incrimination (and this can spend a lot of time in court before anything happens).
