Password Strength Checker
Check how strong your password is. Analysis happens in your browser — the password value is not submitted to NHM.
Checked in your browser. The checker makes no network requests, so your password never leaves your device.
Why Password Strength Matters
Weak and reused passwords are one of the most common ways businesses get breached. In Verizon's 2026 Data Breach Investigations Report, stolen credentials started 13% of breaches, and phishing, which is usually after a password, started another 16%. A strong, unique password for every account, with MFA on top, closes most of that door.
This tool checks your password in your browser — the password value is not submitted to NHM or stored by the checker. 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.
