FAQ

What factors does password strength checking mainly look at?

It typically combines length, character complexity, common words, repetition patterns, and combination rules to judge overall password security.

Why might a long-looking password still be insecure?

If the password contains common words, simple sequences, repeated characters, or easily guessable patterns, even with longer length, actual security may not be high.

What reference value does estimated password cracking time have?

It helps you more intuitively understand current password strength level, but specific risk still varies based on attack methods, system policies, and breach situations.

Is it suitable for checking passwords before registering accounts?

Very suitable. Check first before setting to reduce probability of using weak passwords and improve basic account security level.
