Question 1

What does the password policy generator create?

Accepted Answer

The password policy generator creates a regular expression (regex) that validates whether a password meets your specified rules. You can define minimum/maximum length, required character types (uppercase, lowercase, numbers, special characters), and restrictions like no spaces or no consecutive repeated characters.

Question 2

How do I use the generated regex in code?

Accepted Answer

The generated regex can be used in JavaScript with the test() method: /yourRegex/.test(password), or in other languages with their regex validation functions. In HTML, you can use it in the pattern attribute of an input element for client-side validation.

Question 3

What is the no-repeating characters rule?

Accepted Answer

The maximum repeating characters rule prevents a character from appearing consecutively more than the specified number of times. For example, setting max repeat to 2 rejects passwords where any character appears 3 or more times in a row (e.g., aaa123 would be rejected). Setting it to 0 disables this rule.

Question 4

What strength score does the password tester use?

Accepted Answer

The tester calculates a 0-3 score based on password properties: +1 for length 8+, +1 for length 12+, +1 each for uppercase, lowercase, numbers, and special characters. Scores map to weak, fair, strong, and very strong labels regardless of whether the password meets your policy rules.

Question 5

Should I use the same regex on both client and server side?

Accepted Answer

Yes, for security critical applications you should validate passwords on the server side as well. Client-side validation improves UX but can be bypassed. Use the same regex pattern in your backend API to ensure consistent enforcement of your password policy.
