Check password strength without sharing your password
Use an invented example with a similar length and character pattern to understand what makes a password easier or harder to guess.
Never enter a password you currently use. Even though this checker works locally in your browser, the safest practice is to test an invented example with a similar pattern.
Local password check
Test an example
Strength is based on length, character variety, and common patterns. This is guidance—not a guarantee or an exact crack-time prediction.
Nothing entered here is submitted by this checker. Use a fictional example anyway.
Enter an exampleAim for a long, unique passphrase.
- Longer is usually stronger than simply adding one symbol.
- Every account should use a different password.
Local password generator
Create a random password
The generator runs in your browser and uses crypto.getRandomValues, the browser’s cryptographically secure random-number source.
Save generated passwords in a reputable password manager. Do not reuse them across accounts.
Stronger account security
A password is only one layer.
Better passwords matter, but account protection also depends on how credentials are stored, reused, and verified.
Use unique passwords
A separate password for every account limits the damage when one service is compromised.
Use a password manager
A reputable manager can generate and store long, unique credentials so people do not have to remember each one.
Turn on MFA
Multi-factor authentication adds another verification step and can reduce the risk created by a stolen password.
How this checker works
The result is intentionally practical, not theatrical.
The checker looks at length, upper- and lowercase letters, numbers, symbols, repeated characters, sequences, and a short list of common password patterns. It returns a relative strength level and improvement tips. It does not claim to know an exact crack time because real outcomes depend on the attack method, password storage, computing power, rate limits, multi-factor authentication, and whether the password has appeared in a breach.

Passwords are one part of a practical security program.
