How to use

Check strength locally, then improve the weak spots

The Password Strength Checker estimates how hard a password is to guess using length, character variety, entropy, and simple pattern checks. It is a practical guide, not a guarantee against every attack method.

Open the tool

Step 1

Enter the password

Type or paste the password you want to evaluate. The checker runs locally and does not upload the value.

Step 2

Read the score and entropy

Use the strength label, score meter, and entropy estimate to understand how resistant the password looks against guessing.

Step 3

Fix pattern warnings

Watch for short length, low variety, repeated characters, keyboard patterns, and common-password matches.

Step 4

Generate a stronger replacement

If the password is weak, open the Password Generator and create a unique, longer password for that account.

Practical tips

Prefer 12+ characters for important accounts.
Mix lowercase, uppercase, numbers, and symbols when possible.
Avoid dictionary words, birthdays, and keyboard walks like qwerty.
Never reuse the same strong password across sites.
Store unique passwords in a password manager.
