What is A Lock Screen

I recently got into this small debate with my friend about lock screens, and honestly, I started wondering about it myself. I know it’s that screen you see before you unlock your phone, laptop, or whatever, but like, is that all there is to it? Are there any cool ways to customize it or use it better? I mean, I’ve seen people have fancy wallpapers, widgets, and even shortcuts on their lock screens, and I’m like, am I missing out on something here? Also does the lock screen even matter for security, or is it just for looks? Like, what’s the point of customizing it? Anyway if you guys know any tips, tricks, or just want to share how you’ve set up your lock screen, please drop some ideas. I’d love to hear what you all think
