Apple has upped the ante when it comes to device security to Two-factor Authentication. Two-factor Authentication increases the security on your various devices by requiring an authorization code to login in addition to your normal password. I have been running Two-factor Authentication for quite a while now. It is definitely more of a hassle, but way more secure than previous login forms. I recommend using it. If you are not using it and would like to try it out, go to this article on the Apple website which explains how to set it up on different Apple devices and operating systems.
