Is my password sent to a server to be checked?

No — the strength check runs entirely in your browser using JavaScript; your password is never transmitted.

How is the strength score calculated?

It combines length, character variety (uppercase, lowercase, numbers, symbols), and penalties for repeated characters or common passwords.

Does a high score guarantee my password is safe?

It indicates resistance to common guessing patterns, but no scoring tool can guarantee safety against every possible attack — using a password manager with unique passwords is still recommended.

Why did a long password still score poorly?

It may be one of the most commonly used passwords, or rely heavily on repeated or sequential characters, both of which are penalized.

Should I check my real, in-use passwords here?

Since the check is entirely local and never transmitted, it is safe to check real passwords, though using a freshly generated password is always a stronger choice.

What is considered a strong score?

Scores of 80 and above indicate a very strong password; 60-79 is strong; below that, the specific feedback shown will explain what to improve.

What Is a Password Strength Checker?

A password strength checker analyzes a password's length, character variety and common weaknesses — like repeated characters or being one of the most commonly used passwords — to give an at-a-glance score and specific feedback on how to make it stronger.

It is a quick way to sanity-check a password before using it, without needing to memorize security best practices — the tool tells you exactly what's missing, such as a missing symbol or insufficient length.
