Frequently Asked Questions
What makes a strong password?
A strong password has at least 12 characters, includes uppercase and lowercase letters, numbers, and symbols, and avoids common words or patterns.
Is my password stored or transmitted?
No. All analysis happens locally in your browser. Your password never leaves your device.
What is a brute-force attack?
A brute-force attack tries every possible character combination until the correct password is found. Longer passwords take exponentially longer to crack.
Should I use a password manager?
Yes. Password managers generate and store strong unique passwords for each site, so you only need to remember one master password.
What is the most common weak password?
Passwords like 123456, password, qwerty, and abc123 are among the most common and can be cracked instantly.
