Password Strength Checker
Check how strong your password is. Everything happens in your browser — your password is never sent anywhere.
100% client-side. Your password never leaves your device — no network requests are made.
Why Password Strength Matters
Weak passwords are one of the most common ways businesses get breached. According to Verizon's Data Breach Investigations Report, over 80% of hacking-related breaches involve weak or stolen credentials. A strong, unique password for every account is your first line of defense.
This tool checks your password entirely in your browser — it is never sent over the network or stored anywhere. We evaluate length, character variety, common patterns, and calculate entropy to estimate how long it would take to crack using modern hardware.
Password Best Practices
Use a Password Manager
Generate and store unique, strong passwords for every account. You only need to remember one master password.
Enable MFA Everywhere
Multi-factor authentication adds a second layer of protection even if your password is compromised.
Use Passphrases
Four or more random words strung together (e.g., 'correct horse battery staple') are both strong and memorable.
Never Reuse Passwords
If one account is breached, reused passwords give attackers access to all your other accounts.
