Password Generator
Create a strong, random password. Everything is generated locally in your browser - your password is never sent anywhere.
Why password strength actually matters
Weak or reused passwords are one of the most common ways online accounts get compromised. Attackers don't typically guess passwords one at a time — they use automated software that can attempt millions of combinations per second, working through dictionaries of common passwords and known data breach leaks first. A short or predictable password can be cracked in seconds, while a sufficiently long, random password with mixed character types can take an impractically long time to crack through brute force alone.
This tool generates passwords using your browser's cryptographically secure random number generator (the Web Crypto API), which is specifically designed for security-sensitive applications, rather than a simple pseudo-random function that can produce predictable patterns.
Why length matters more than complexity
A common misconception is that adding a single special character to a password makes it dramatically more secure. In reality, password length has a bigger impact on crack-resistance than character variety alone — each additional character exponentially increases the number of possible combinations an attacker would need to try. A longer password using only letters and numbers is often more secure than a shorter one stuffed with symbols.
Why you shouldn't reuse passwords
When a website suffers a data breach, attackers often try the leaked username/password combinations against other popular sites, a technique called credential stuffing. If you reuse the same password across multiple accounts, a breach on one relatively unimportant site can expose your more sensitive accounts elsewhere. Using a unique, randomly generated password for each account — ideally stored in a password manager rather than memorized — eliminates this risk entirely.
How long should my password be?
Most current security guidance recommends at least 12-16 characters for accounts that matter, using a mix of character types where the website allows it.
Is it safe to generate passwords online?
This tool generates the password entirely in your browser using JavaScript's cryptographically secure random number generator — it is never sent over the network or logged anywhere, so it's as safe as generating one on your own device offline.
Why does the password exclude certain characters like 0, O, l, and 1?
This tool deliberately avoids visually similar characters (like the number zero and the letter O) in some character sets to prevent confusion if you ever need to manually type the password rather than paste it.
Should I write my password down?
A password manager is generally considered more secure than writing passwords down or memorizing simplified versions, since it lets you use long, fully random passwords for every account without needing to remember them yourself.
