Why people use zxcvbn
Password Strength Evaluator for SecOps Credential Audits
Now, you can hand that task to your agent. It uses the zxcvbn engine to run every password through a mathematical check. It identifies common dictionary words, repeated characters, and easy sequences instantly. You get a clear score and a crack time estimate, letting you focus on the real threats instead of manual checking.
What Vinkius changes
You get math-based security scores instead of lucky guesses.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.

- Real-world use case 01
Auditing leaked databases
An engineer finds a list of leaked passwords and asks the agent to use evaluate_password to flag any that can be cracked in under a year.
- Real-world use case 02
User onboarding
A new user tries to set a weak password and the agent uses evaluate_password to tell them it's too common.
- Real-world use case 03
Policy validation
A security lead wants to see if '12 characters' is actually enough for their specific user base using evaluate_password.

Before you connect
Questions about zxcvbn.
The practical details behind the request, access and result.
How does Password Strength Evaluator help with security audits?
It automates the process of checking thousands of credentials for weakness. Your agent can run every password through an entropy test and flag the ones that are most likely to be cracked by hackers.
Does Password Strength Evaluator use a real math engine?
Yes, it uses the zxcvbn engine. This means it looks at things like dictionary words and common patterns instead of just checking for symbols or numbers.
Can I use Password Strength Evaluator to set password policies?
Absolutely. You can ask your agent to only accept passwords that get a score of 3 or higher. This ensures your users are choosing truly strong credentials.
How accurate are the crack time estimates?
The capability provides estimates based on local fast hashing. It tells you how long a standard brute-force attack would take to guess the password.
Can Password Strength Evaluator help me find leaked passwords?
You can give your agent a list of plain-text passwords from a leak. It will evaluate each one and tell you which ones are the highest risk so you can prioritize your response.
Is the evaluation done locally?
Yes, the calculation happens locally. This means your sensitive password strings don't need to be sent to an external third-party service for scoring.
Is the password sent to any API?
No. The evaluation runs 100% local within the secure V8 Edge isolate, ensuring zero data leakage.
What is the score range?
It returns a score from 0 (very weak) to 4 (very strong). We recommend rejecting any password with a score below 3.
Does it detect common patterns?
Yes, it detects dates, names, sequential keyboard patterns (like 'qwerty'), and common dictionary words.
