What does the password strength checker do?
It analyzes a password and gives you a strength score from Very weak to Very strong, along with specific, actionable feedback on how to improve it.
How to use it
Type or paste a password into the input field. The strength bar and feedback update in real time. The feedback tells you exactly what to add or change for a stronger password.
Example
The password 'hello' scores Very weak with feedback to add uppercase, numbers, symbols, and length. The password 'K7#mQ2$vLp9!xR4n' scores Very strong.

FAQ
Is it safe to type my real password?+
The checker runs entirely in your browser — no network request is made. However, if you're concerned, use a variation of your password pattern rather than the exact password.
What makes a password strong?+
Length (12+ characters), a mix of uppercase, lowercase, numbers, and symbols, and avoiding common patterns like 'password', '123456', or dictionary words.
