I'm using a necklace with an NFC tag that automatically sticks to my skin (https://www.amazon.com/RapidNFC-Pack-tags-NTAG213-transparents/dp/B008JW5QZ0). This lets me unlock my Android smartphone with the app or built-in "Smart Lock" feature. It's easy - I just need to get close to my phone and it unlocks.
