Credential Stuffing

Attackers use leaked credentials to try logging into other accounts. Reusing passwords increases the risk, but tools like account compromise checkers and password leak checkers can help.

Data Breaches

Large breaches expose millions of passwords. Using the same password across sites is risky, but dark web scans and "check if email is compromised" tools can alert you.

Predictable Password Patterns

Even modified passwords often follow predictable patterns. Monitoring for leaked passwords and running dark web exposure checks helps you stay protected.
