I’m going to say something wildly unpopular. With every data breach, our “personal data” becomes a lot less personal and a bit more public. Time to start treating your name, ID numbers (DL, SSN), and contact information like a license plate - visible to everyone, but basically useless except those who have the keys to use it.
In other words, freeze your damn credit bureaus unless you need them open. Use multi factor authentication everywhere you can. Secure with biometrics when possible. Do that, and you just get used to the fact that this data is out there and you’ve now made it nearly worthless to those who try to use it.
Edit to add: I’m not saying you need to be happy or support companies that don’t respect and secure your data. I say this as a POed T-Mobile customer.
