Password Strength Checker FAQ
Is it safe to type my password into this tool?
Yes. The check runs entirely on your own device in the browser. Your password is never sent to a server, logged, or stored. That said, as a habit, never enter a real password into a tool you do not trust.
What does the crack time mean?
It estimates how long a fast offline attack (billions of guesses per second) would take to find your password by brute force. Longer and more varied passwords push this from seconds to millions of years.
What is entropy?
Entropy measures how unpredictable a password is, in bits. More bits means more possible combinations and a harder password to guess. Around 70 bits or more is considered strong.
Why is my long password still rated weak?
Length helps, but common words, repeated characters, and sequences like "123" or "abc" are easy to guess and lower the score. The tips will point out exactly what to fix.
Do I need to sign up?
No. The password strength checker is free with no account and no limits.
