Eh, it’s probably been on the dark web for a while now given how frequent and massive data leaks have become. Worry more about unauthorized use/access to your credit and/or identity.
Place freezes on your credit for Experian, TransUnion, and Equifax (it’s free)
Lock any credit cards you don’t use regularly
Pull your credit reports from each agency (you get one a year for free) and verify activity
Enable balance notifications for your credit cards and bank accounts (eg, high transaction amount = $0.00 will alert you to every purchase made)
Don’t use the same password for multiple websites. If you don’t already, use a password manager like KeePass and let it generate new passwords for you
It’s all about the diligence these days. Your morning should be fine. The worst thing you can receive is a high transaction amount alert you didn’t authorize. But card companies and banks have gotten good about dealing with those when they happen.
