Frequently Asked Questions
Does this send my password anywhere?
No. The strength check runs entirely in your browser with plain JavaScript — your password is never sent to a server, logged, or stored anywhere.
What makes a password strong?
Length matters most — 12+ characters is a good baseline. Mixing uppercase, lowercase, numbers, and symbols, and avoiding repeated characters or common patterns, all increase strength.
Should I use a password manager instead?
Yes — a password manager can generate and store long, unique, random passwords for every site, which is far more secure than memorizing variations of the same password.
