Why use Ozaar Password Generator?
Cryptographically secure
Uses window.crypto.getRandomValues(), the same source of randomness used by security professionals and operating systems.
Fully customisable
Choose length, include/exclude uppercase, lowercase, numbers, symbols. Build exactly the password format you need.
Real-time strength meter
See your password strength rated from Weak to Very Strong as you adjust settings, with entropy bits displayed.
Bulk password generation
Generate and copy up to 50 unique passwords at once, perfect for seeding a new team or batch-updating accounts.
Real-world use cases

What is a Password Generator?
A password generator is a tool that creates random, unpredictable passwords based on your specified requirements. Unlike manually chosen passwords (which tend to be predictable, reused, or too short), a properly generated password uses true randomness to produce a string that is computationally infeasible to guess or crack.
Password security is one of the most consequential and most overlooked aspects of personal and business cybersecurity. The vast majority of account compromises occur because of weak, reused, or breached passwords, not because of sophisticated hacking. A strong, unique password for every account is the single most effective defence against credential-based attacks.
Ozaar Password Generator uses the browser's built-in cryptographic random number generator to produce passwords that meet the highest security standards, with customisable length, character sets, and bulk generation.
How does Password Generator work?
Our generator uses window.crypto.getRandomValues(), the browser's implementation of a Cryptographically Secure Pseudorandom Number Generator (CSPRNG). This is the same source of randomness used in cryptographic applications, TLS certificates, and operating system entropy pools. It is mathematically impossible to predict the next value from previously observed values.
Character selection uses a modulo-reduction technique with rejection sampling to ensure each character position has an exactly equal probability of being any character in your chosen set, avoiding the statistical biases that affect simpler random() implementations.
Why use a browser-based Password Generator?
Running the password generator in the browser means your generated passwords are never transmitted anywhere. Many cloud-based password generators (including some high-traffic ones) generate passwords server-side, which creates a theoretical risk that generated passwords could be logged or intercepted. Our generator has no server component.
There is also no account needed, no generated passwords saved, and no usage analytics. The only record of your generated password exists in your clipboard, and only until you replace it.
You might also want to generate a QR code linking to your account or analyse the strength of passphrase words using our free browser tools.
