Entropy measures randomness. A 16‑character password using all character types has over 100 bits of entropy — requiring billions of years to brute‑force at modern hardware speeds.
All generation happens in your browser using the Web Crypto API. No passwords are transmitted, logged, or stored. Your secrets stay with you.
Never reuse passwords across platforms. One breach can compromise every account. Use a trusted password manager to securely store unique credentials.
Understanding Entropy Passwords
The Core Concept
If you create a password like '123456,' it has almost zero entropy. Why? Because the next character is easy to guess, leaving no room for 'surprise.' However, if you generate a string like '2V0btSi-z:VVdJj3,' the next character is nearly impossible to predict. This high level of unpredictability is what we call High Entropy. A secure password is one where every character is statistically impossible to guess, creating the 'surprise' factor that effectively stops hackers.
The Scale
We use 'bits' to measure password strength. 128 bits is widely considered the gold standard for security. By reaching 104+ bits, your passwords shift the difficulty of a brute-force attack from 'seconds to crack' to 'billions of years to crack.' While weak passwords can be compromised in seconds, our 100+ bit passwords would take even the most powerful supercomputers billions of years to break.
Usability Optimization
We know high-security passwords are hard to memorize. That's why we focus on 'Entropy-Based Security' to create complex, randomized strings for your most important accounts. These high-entropy strings provide maximum protection; simply save them in a trusted password manager to stay secure without the burden of memorizing complex characters. We recommend:
No Server Contact: All generation happens locally in your browser. We never see, store, or transmit your passwords.
User Responsibility: You are responsible for the security of any generated password. We recommend using a dedicated password manager.
