Password Security FAQs
What makes a password strong?
A strong password should be at least 12 characters long, include a mix of uppercase and lowercase letters, numbers, and special characters. Avoid common words, phrases, or personal information.
How does this tool estimate crack time?
We calculate the possible combinations based on password length and character variety, then estimate how long it would take a modern computer (testing 1 billion combinations per second) to brute-force your password.
Is my password safe with this tool?
Yes! All password checking happens in your browser only. We never send your password over the internet or store it anywhere.
How often should I change my passwords?
For critical accounts (email, banking), change passwords every 3-6 months. Use unique passwords for each account and change immediately if a service reports a breach.
