Question 1

Why is my password score low?

Accepted Answer

We use the Zxcvbn algorithm developed by Dropbox. It doesn't just check length; it detects common dictionary words, sequential characters (like 12345), common keyboard patterns (like qwerty), and repetitive strings. If your password is predictable, the score drops.

Question 2

What does 'Exclude Ambiguous Chars' do?

Accepted Answer

In some fonts, a lowercase 'l', an uppercase 'I', and the number '1' look nearly identical. The same applies to uppercase 'O' and the number '0'. Excluding these prevents visual confusion when sharing or writing down passwords.

Question 3

Is this tool safe? Are my passwords stored?

Accepted Answer

100% safe. This tool runs entirely in your browser's local memory. No data is ever sent to a server. We don't even have a database for this tool, so your passwords never leave your device.

Question 4

Who needs the batch generation feature?

Accepted Answer

System administrators, IT operations, or developers who need to quickly create secure credentials for new employees or test accounts. Batch exporting to JSON or CSV makes it easy to import them into password managers or scripts.

Question 5

Why is the password strength rating different from Google or other websites?

Accepted Answer

Traditional password checkers (like early Google or most websites) often rely on simple rules, such as checking if it contains uppercase, numbers, and symbols. This allows weak passwords like `Password123!` to score highly. We use the Zxcvbn algorithm (open-sourced by Dropbox), which utilizes massive dictionaries of leaked passwords, names, and detects spatial/keyboard patterns (like `qwerty`). It evaluates passwords based on real-world hacker cracking techniques, making its scoring much stricter and more scientifically accurate.
