If you follow the news you’re probably aware of all the data breaches involving stolen passwords that have taken place of late.
The sad fact is there’s absolutely nothing you can do to prevent hackers from stealing your passwords and other sensitive info if they can somehow manage to break into the servers that are storing them.
About the only things you can do on your end is make sure you choose passwords that are secure and take care to avoid falling for phishing attempts.
But the above being said, there’s a settings change you can make to most any online account that will make it very difficult for a hacker to break into that account even if they somehow manage to get your password.
