My roommate is able to get into my phone no matter how I like it what can I do

[AC Question]

No matter what I do my roommate keeps getting into my phone. What is the best security

I'd break his fingers.
Two step verification is the strongest way to go

I tend to agree with this suggestion. Considering how much of our lives we intertwine with our phones it's a real invasion of privacy to just pick up and starting using a phone that belongs to someone else without permission.
But just to clarify, is this a matter where you have a lock screen set up and your roomie knows your password/pattern/PIN/whatever, or is it a issue where your roomie is logging into your social services account(s) and essentially 'getting into' your phone online?

Password, use something different, nothing you'd normally use. No birthdays, no names, and the like. Use random things. And then use the same letters multiple times, and add numbers to the letters. Like maybe Andr0idc3ntral, like that. Then don't use the password a lot, just the fingerprint sensor, so you dont leave finger grease.
