You can use email aliases or even go as far as a phone alias as well.

Been using Mozilla relay for a while and the phone number option is nice to mask your real number for some things.

It does report as a VOIP number so some services can't use it.

The scariest threat in the event you're affected by the data breach is if someone has enough information to open credit in your name. There's a website you can look yourself up on. I have it in my pc I think, but not my phone. They have my name and ssn, but an old address that's not valid any more. Maybe someone can link it. I'll see if I can find it in the morning if no one does.

2FA is good to use when available.

That's mainly it. It could be the most likely threat is to email you scary things to try to get you to click on the wrong thing. Or calling you up with the classic threat that the sheriff is on his way to arrest you now over some outstanding debt. I know wtf I'm doing with security and I've still fallen for a phishing scheme (caught it before any harm was some, but still clicked the damn email). My wife fell for the sheriff thing—sucks when they do find a blemish on your credit to really sell you on they are a real debt collector.

Not worried necessarily. But as a suggestion, you could use different email addresses for different purposes. I use 1 address each for;

1. Family
2. Friends
3. Banking & Financial Services
4. Shopping
5. Lists I'm subscribed to (not related to the above)
6. Forums
7. Social Media
8. Junk And I use an email client to stay up to date with those accounts. That way when your Shopping email claims your bank has been hacked, you immediately know it's a scam because they are not connected.
