Like other smart locks, August’s lets you open or lock your door using a companion mobile app. We gave it a score of 80 for a number of reasons, the first being its easy installation process. The mobile app guides you through simple instructions to attach the smart lock to your door and you’ll be asked to enable two-factor authentication for your account, making it a bit more secure then other IoT setups that make that step optional. It attaches to your existing deadbolt and it took us only about 10 minutes to install. The lock doesn’t dominate your door
