Frequently Asked Questions
How is password strength calculated?
We check for minimum length (8 and 12 characters) and whether your password contains uppercase letters, lowercase letters, numbers, and special characters.
Is my password sent to any server?
No. Everything happens entirely in your browser. Your password is never transmitted or stored anywhere.
What makes a password very strong?
A very strong password has at least 12 characters and includes all four character types: uppercase, lowercase, numbers, and special characters.
Can I use this with the Password Generator?
Yes! Generate a random password with our Password Generator, then verify its strength here to make sure it meets all requirements.
How strong is your password?
A password strength checker rates how hard a password would be to crack and estimates how long it might take an attacker to guess. It looks at length, the mix of character types and common patterns, then gives clear feedback.
It helps you understand why a password is weak before you rely on it.
