Why Reusing Passwords Is Dangerous: Lessons from the Gmail Credential Leak

As you may have seen in the news, a massive data leak has exposed over 183 million email and password combinations, including tens of millions linked to Gmail accounts. While this was not a direct breach of Google, the credentials were collected through malware, phishing, and malicious downloads.

Just as we covered in our cybersecurity training, please do not reuse passwords across different services. Reused credentials are especially vulnerable to credential stuffing attacks, where attackers try the same email-password combinations across multiple sites.

To stay secure, we strongly recommend:

• Using a password manager to generate and store unique passwords for each account.
• Enabling multi-factor authentication (MFA) wherever possible.
• Being cautious of suspicious emails or links, especially those asking for login information

If you’re unsure whether your credentials have been compromised, you can check at . If your account is listed in a leaked database or affected service, please change your password immediately anywhere that password has been used.
 
Let’s all stay vigilant and continue practicing good cyber hygiene.
