Create strong, random, unpredictable passwords instantly with full control over length and character sets.
A password generator is one of the simplest yet most effective tools you can use to protect your online accounts. Most people still choose passwords based on names, birthdays, or common words, which makes them easy targets for attackers using dictionary attacks or credential-stuffing scripts. This Password Generator removes human guesswork from the equation entirely by using your browser's cryptographically secure random number generator (crypto.getRandomValues) to build a password from scratch, character by character, with no predictable pattern whatsoever.
Unlike many online generators that quietly send your request to a server, this tool runs completely inside your browser. Nothing about the password you generate — not the length, not the character options, not the final result — ever leaves your device. That matters because even a password generator itself can become an attack vector if it logs what it creates. Here, the entire process happens in local JavaScript memory and is gone the moment you refresh the page.
Security researchers generally agree that password length contributes more to real-world resistance against brute-force attacks than symbol complexity alone. A 20-character password using only lowercase letters can be harder to crack than an 8-character password stuffed with symbols, simply because of the sheer number of possible combinations. That's why this tool lets you push length up to 64 characters, while still giving you full control over uppercase, lowercase, digits, and symbols if a particular website enforces its own character rules.
One common complaint with generated passwords is confusion between characters that look alike when typed manually or read off a screen — for example, a lowercase "l", an uppercase "I", the digit "1", the letter "O", and the digit "0". If you plan to write the password down temporarily, read it aloud, or type it manually into a device where copy-paste isn't available, enabling the "Exclude ambiguous characters" option removes this entire class of confusing characters while keeping the password just as random.
Below the generated password, a strength meter gives you an immediate visual signal of how resistant the result is to guessing, based on length and the diversity of character types used. This is a simple heuristic, not a substitute for the more detailed analysis offered by our dedicated Password Strength Checker tool — but it gives you fast, at-a-glance feedback so you're not left wondering whether the settings you picked are actually producing something strong.
Always generate a unique password for every account. Reusing even a strong password across multiple sites means that if one service suffers a data breach, every other account sharing that password becomes vulnerable too. Pair this generator with a reputable password manager so you never have to memorize dozens of long random strings — you only need to remember one strong master password. Also consider enabling two-factor authentication wherever it's offered; a strong password combined with 2FA is one of the most effective defenses available to everyday users against account takeover.
Yes. The entire generation process runs locally in your browser using the Web Crypto API's cryptographically secure random number generator. No password, setting, or keystroke is ever transmitted to any server.
For most personal accounts, 16 characters is a strong baseline. For highly sensitive accounts such as your email or password manager master password, consider 20 characters or more.
Yes, simply uncheck the Symbols option. Some legacy websites restrict allowed characters, and the generator will still produce a strong password using only the character sets you select.
It's mathematically possible but astronomically unlikely with sufficient length and character variety, similar to the odds involved in any cryptographically random process.
No. Nothing is saved to local storage, cookies, or any server. Once you navigate away or refresh, the generated password is gone unless you've copied or saved it yourself.
