Security Tips

1
Change your passwords immediately. If your email appears in any breach, change passwords for all accounts using that email, starting with financial and email accounts.
2
Enable two-factor authentication (2FA). Add an extra layer of security to your accounts by enabling 2FA wherever available.
3
Use unique passwords for each account. Never reuse passwords across different services. Use a password manager to generate and store strong, unique passwords.
4
Monitor your accounts for suspicious activity. Regularly check your financial statements and account activity for any unauthorized access.
5
Be cautious of phishing emails. Breached data is often used for targeted phishing attacks. Never click on suspicious links or provide personal information in response to unsolicited emails.
6
Consider using a password manager. Tools like Bitwarden, 1Password, or KeePass can help you generate and manage strong, unique passwords for all your accounts.
7
Freeze your credit if necessary. If sensitive financial data was exposed, consider placing a credit freeze with the major credit bureaus to prevent identity theft.
