If a store alerts you to a data breach, what should be your immediate reaction?

Changing your passwords is the most immediate and effective action to take if you are alerted to a data breach. This is crucial because a data breach often means that sensitive information, such as usernames and passwords, may have been exposed. By updating your passwords for accounts that may have been compromised, you can reduce the risk of unauthorized access to your accounts.

It's also wise to focus on strong password practices, such as using unique passwords for different accounts and incorporating elements like numbers, symbols, and both uppercase and lowercase letters. Doing so helps protect your accounts better against potential unauthorized access. While the other options may be valid responses to identity theft concerns, changing passwords is the first step in mitigating immediate risks following a data breach alert.
