Create ultra-secure, highly customizable passwords instantly.
Define exactly which symbols you want to allow in your password:
A password generator is a specialized security tool designed to create strong, randomized passwords that are resistant to brute-force attacks, dictionary attacks, and social engineering. Unlike human-created passwords—which tend to follow predictable patterns like names, birthdays, or common words—a properly engineered password generator uses cryptographic randomness to produce strings with maximum entropy. The strength of a password is measured in bits of entropy: a 16-character password using uppercase, lowercase, numbers, and symbols provides roughly 105 bits of entropy, which would take billions of years to crack with current technology. Our generator uses the Web Crypto API's crypto.getRandomValues() method, which is a cryptographically secure pseudo-random number generator (CSPRNG) built directly into your browser's engine.
Most online password generators send your request to a remote server, which briefly generates and transmits the password back to you—meaning your newly created password exists on someone else's infrastructure, even if only for a fraction of a second. Our tool eliminates that risk entirely. Every password is generated exclusively within your browser's JavaScript runtime using the native Web Crypto API. There is no network request, no server-side processing, and no database logging whatsoever. Additionally, our generator offers granular control that many alternatives lack: you can define the exact set of special characters allowed (useful when a website restricts certain symbols), set precise lengths from 4 to 64 characters, and mix character categories to meet any password policy requirement.
Security experts recommend a minimum of 12 characters, but 16 or more is ideal for critical accounts like email, banking, and cloud storage. Our generator supports passwords up to 64 characters. Each additional character exponentially increases the time required for a brute-force attack.
Yes, when the tool runs entirely client-side like ours does. Our password generator uses the Web Crypto API built into your browser, which provides cryptographically secure random numbers. The generated password exists only in your browser's memory and is never transmitted over the internet.
Some legacy systems and poorly coded websites restrict special characters because they can cause issues with databases, authentication protocols, or character encoding. Our tool lets you customize exactly which symbols are included to comply with any website's specific password policy.
Absolutely. Reusing passwords is one of the most dangerous security practices. If one service is breached, attackers will try that same password on other sites—a technique called credential stuffing. Use this generator to create a unique password for every account.
