Tips

- Use a different password for every important account, ideally with a password manager.
Frequently Asked Questions (FAQ)
How is my password scored?
The score checks length, use of upper and lower case letters, digits, symbols, and common weak patterns like repeated characters, sequences and dictionary words. Everything runs in your browser and nothing is sent anywhere.
What does the crack time estimate mean?
It is a rough estimate of how long a brute force attack would need at 10 billion guesses per second. Use it to compare passwords, not as a guarantee.
How can I make my password stronger?
Add length first, then mix upper and lower case letters, digits and symbols, and remove repeated characters, sequences and dictionary words. The How to make it stronger section gives tips based on your result.
Is it safe to type my real password here?
Yes. All checking happens locally in your browser on your own device. Your password is never uploaded, stored or logged.
