Password Pattern Validator
Validate passwords against custom patterns, entropy requirements, and common password lists. Create and test password policies for your applications.
Password is validated locally and never sent to any server
Password Requirements
Password Security Tips
- Use at least 12 characters for strong passwords
- Mix uppercase, lowercase, numbers, and symbols
- Avoid common words and personal information
- Use a unique password for each account
- Consider using a password manager
Why Validate Password Patterns?
Strong password policies are essential for security. This tool helps you test password requirements and ensure users create secure passwords.
Frequently Asked Questions
What is password entropy?
Entropy measures password randomness in bits. Higher entropy means more possible combinations and greater security against brute-force attacks.
Why block common passwords?
Attackers use lists of common passwords in credential stuffing attacks. Blocking these prevents users from choosing easily guessed passwords.
What are sequential characters?
Sequences like 'abc', '123', or 'qwerty' are easily guessed. Blocking these improves password security.
How much entropy is enough?
Aim for at least 60 bits of entropy for strong passwords. This tool calculates entropy based on character set size and length.
