Google Smart Lock is a feature that allows users to automatically unlock their devices, such as phones and laptops, when they are signed in to Google accounts. When you launch Spotify, it checks to see if you are signed in to a Google account. If you are, then Smart Lock will turn on and allow you to use Spotify without having to enter your password each time. If you’re not signed in to a Google account, then Smart Lock won’t turn on and you’ll need to enter your password each time you launch Spotify. ..
