[ARCHIVED] Storing Passwords in your Browser Can Ruin Your Life (But Will Make Criminals VERY Happy!)

Grahpic of Cyber Security images such as locks, email, hackers, security breaches

In a kinder, gentler world, you might be able to store all your passwords and logins
in your browser, and it would be safe and convenient. This is not that world;
storing passwords in your browser can be extremely risky.

All browsers allow you to save passwords to websites requiring credentials and while this is convenient it is dangerous because if your computer is compromised the criminals now have access to all your credentials as well.  The recommendation: do NOT use the same computer for gaming or videos that you use for work-related accounts, personal finance/baking, your children's school network, taxes, your patient portal, your health records, or anything personal and sensitive - use a separate device for fun and games.

Typical ways we see computers being compromised

  • You receive an unexpected email
  • You click on a popup box (ex. to allow notifications)
  • You download games

Sometimes, even if your anti-virus says it found malware it wasn't able to stop the exfiltration of your saved browser credentials.
