If your smart lock is connected to a voice assistant, be sure to use a PIN to unlock it with voice commands. It's a stretch, but it is possible to create workarounds with IFTTT to avoid using the PIN. It's also possible for someone outside your home to ask your voice assistant to unlock the door if they have just a few pieces of information about your device.
You can read more about that here, but using a PIN for voice unlocking is an absolute must for smart lock safety. By default Google Assistant and Amazon Alexa both require a spoken PIN for voice unlocking, and you can use one with several smart locks, including the August Smart Lock Pro, the Kwikset Obsidian and Yale's Assure SL Touchscreen Deadbolt.
Individual codes are a great way to not only ensure your safety, but also keep track of who's coming and going from your home. It's a good idea not to pass out just one code for friends, family, guests and commercial services. Most locks include the option for at least 10 codes. Some, like the Nest X Yale lock, allow an unlimited number of individual codes.
