Frequently Asked Questions
Is my password sent to your server when I check it?
No. All strength analysis happens locally in your browser using JavaScript. Nothing is transmitted or logged.
What makes a password strong?
Length matters more than complexity — aim for at least 12 characters, mixing uppercase, lowercase, numbers, and symbols, while avoiding common words or predictable patterns.
Should I reuse a strong password across sites?
No — even a strong password should be unique per site. Consider a password manager to generate and store unique passwords for every account.
