🛡️ Password Strength Test

Entropy, crack time & weakness analysis — computed privately in your browser — by Dinal Studios

⚠️ Golden rule: NEVER type a real password into ANY website — including this one. This page runs 100% locally (no server, nothing stored or sent, works offline), but the safe habit protects you everywhere: test a similar but different password to judge your style — then use a password manager to generate the real one.

🔍 Test a Password LOCAL ONLY

Type a test password below. Analysis updates as you type: entropy, pattern weaknesses, and how long different attackers would need to crack it.

⏱️ How Long To Crack It?

Average time to guess half the possibilities, under five attack models. Real attackers start with dictionaries and patterns — which is why the pattern findings below matter more than raw length.

Attack scenarioGuesses / secondEstimated time
Online attack, throttled by the website100 / hour—
Online attack, no throttling10 / second—
Offline attack on a slow hash (bcrypt-style)10 thousand / second—
Offline attack on a fast hash (GPU rig)10 billion / second—
Massive parallel attack (botnet / nation-state)1 trillion / second—

🧪 Weakness Findings

The exact patterns cracking tools (like Hashcat rule sets) try first — after the top-10-million password lists.

💪 How To Make It Stronger

🔒 100% private: the password you type never leaves this page, is never stored, and this page works fully offline. When in doubt, verify with your browser's network tab — it stays silent.
