Password Strength Visualizer

This tool provides a real-time assessment of your password's strength by calculating its entropy. Entropy is a measure of a password's unpredictability. A higher entropy score means a password is more resistant to brute-force guessing attacks. The calculation is based on the length of your password and the variety of characters used (lowercase, uppercase, numbers, and symbols).

As you type, you'll see the strength bar change color and the entropy score update, giving you instant feedback to help you create stronger, more secure passwords. Because this tool runs entirely in your browser, the password you enter is never sent to a server, ensuring it remains completely private.
