Steps to protect financial accounts exposed in a data breach:
Close all affected accounts and have account numbers changed. This includes checking and savings accounts, money market funds, stocks, brokerage accounts, etc.
Cancel all affected credit and/or debit cards.
No matter what the breach notification tells you, assume passwords and usernames were breached. Change usernames and passwords anywhere else you use the same ones.
Set up two-factor authentication on your accounts, using a PIN, facial or fingerprint ID on your device, or, ideally, having a security code emailed or texted to you to confirm your identity.
Set up email or text alerts on your financial accounts to notify you immediately of new activity
Review your account statements closely for fraudulent transactions.
