Here are a few ways to protect your online accounts from credential stuffing attacks:

1. Use complex passwords: Make sure to create passwords that are complex and difficult to guess. Include a combination of letters, numbers, and symbols. Avoid using common words or phrases that can be easily guessed.
2. Enable two-factor authentication: Use two-factor authentication whenever possible. This will add an extra layer of security when accessing your IDs and accounts.
3. Don’t reuse passwords: Create a unique password for every account you have. Reusing passwords increases the risk of a single breach compromising much more than you initially thought.
4. Check websites for security breaches: Regularly check your favorite websites to see if they have experienced a data breach. If they have, change your login information immediately.
