Password Reuse Checker
Analyze password reuse risks and generate unique alternatives
Add Passwords to Check
All passwords are processed locally. Nothing is sent to any server.
Generate Unique Passwords
Generate unique, strong passwords for each service to replace reused ones.
Why Password Reuse is Dangerous
Credential Stuffing
When one service is breached, attackers use those credentials to access your other accounts. Reused passwords make this trivial.
Cascading Breaches
A single compromised account can lead to email takeover, financial fraud, and identity theft as attackers pivot through your accounts.
Use a Password Manager
Password managers generate and store unique passwords for every account. You only need to remember one strong master password.
No Passwords Added
Add passwords from different services above to check for reuse and get security recommendations.
