Is it safe to type my real password here?

The check runs only in your browser and nothing is sent or saved, but you can test a similar password if you prefer.

How is the crack time estimated?

From the password's length and character variety, assuming an attacker trying 10 billion guesses per second offline.

What makes a password strong?

Length matters most — 12+ characters mixing upper and lowercase, numbers and symbols, with no common words or patterns.

Why is my long password rated weak?

It may contain a common password, repeated characters or a keyboard sequence like 12345 or qwerty, which attackers try first.

Should I reuse a strong password?

No. Use a different password for every account, ideally saved in a password manager.
