You're getting spam texts? Or someone has taken over your number?

Spam texts you can just ignore. Getting a new number isn't guaranteed to reduce the spam, but it's an option.

If your number was taken over, that's a bigger problem. Any other account that's attached to that phone number can be compromised. If that's possible, you're at a point where you need to notify the credit bureaus, your bank, etc.

I've probably accidentally clicked on a million popups since popups first became a thing on the internet. No viruses or malware as a result. Just back out of/kill wherever it takes you to.

1). You visited the porn sites, like all the rest of us do.

2). The only bad thing that could happen is your mom will find out somehow, so just clear your browser history.

Not a huge hassle, but I prefer Touch ID. I have a habit of putting my finger on the reader as I'm taking a phone out of my pocket, which I still do for my Android phones that have biometric scanning. So face ID takes longer for me than unlocking with my finger. Also, when I'm working as a medic and wearing a mask in medical facilities, it's an obvious PITA.
