Frequently Asked Questions
How is password strength calculated?
We use entropy-based calculations and common pattern checks. This includes looking for character variety, length, and the use of easily guessable words or sequences.
Is it safe to type my real password here?
Yes. Our tool runs entirely in your browser. We never transmit your password over the internet or store it on any server. It's completely private.
What is entropy in passwords?
Entropy is a measure of randomness. The higher the entropy (measured in bits), the harder it is for a computer to guess your password through brute-force attacks.
