These are all things we risk losing if we're not careful with our phones while travelling. There's always an increased risk of having a phone stolen or leaving it somewhere when we're on a busy holiday trip. Most phones will activate this by default, but if your phone's screen somehow still unlocks without any password, then you're leaving yourself extremely exposed. That way, if a hacker does manage to get a hold of your phone, then your data will still be safe. If you also have an SD card, then you should also check whether you have any sensitive data on this and this it's encrypted.
