Is my password sent to any server?

No. The strength check runs entirely in your browser. Your password is never transmitted anywhere.

What makes a password strong?

Length is the most important factor, followed by using a mix of uppercase, lowercase, numbers, and symbols. Avoiding dictionary words also matters.

What is password entropy?

Entropy measures how unpredictable a password is, expressed in bits. A higher entropy means the password is harder to guess or crack by brute force.
