Password Generator
Create strong, random, secure passwords instantly. Customize the length and character types to match any website's requirements. No data is sent anywhere — generation happens entirely in your browser.
Why Use a Password Generator?
Weak passwords are the single biggest vulnerability in personal and professional cybersecurity. Humans are terrible at creating truly random passwords — we tend to use names, birthdays, dictionary words, and predictable patterns. Attackers exploit this with automated tools that can guess millions of common passwords per second. A password generator removes human predictability and creates passwords that are mathematically hard to crack.
What Makes a Password Strong?
Strength comes from two factors: length and randomness. A password with 12 characters drawn from a pool of 94 possible characters (uppercase, lowercase, digits, and symbols) has 94^12 possible combinations — roughly 4.7 x 10^23. Even at a billion guesses per second, cracking such a password would take thousands of years. Every additional character multiplies the difficulty by the size of the character pool, which is why length is the most powerful variable you can control.
Character Types Explained
Uppercase and lowercase letters form the foundation of most passwords. Using both increases the pool from 26 to 52 characters. Numbers add another 10 possibilities. Symbols — characters like !, @, #, $, %, ^, &, and * — add the most complexity because they are less commonly used and less predictable. Many websites require a mix of all four types, and our generator lets you toggle each one to meet any requirement.
Avoiding Ambiguous Characters
Some characters look very similar depending on the font: the number zero (0) and the capital letter O, the number one (1) and the lowercase letter l (L), and the capital letter I (i). If you need to type a password manually — for example, into a device with a difficult paste function — excluding these ambiguous characters prevents frustrating mistakes. Our generator offers this as an optional setting.
Password Length Recommendations
For everyday online accounts, 12 to 16 characters is sufficient when combined with all character types. For sensitive accounts like email, banking, or cryptocurrency wallets, use 20 characters or more. If a website allows passphrases (long sequences of random words), those can be even more secure and easier to remember — but when you need a random string, longer is always better.
How to Use This Tool
Adjust the length slider and check the character types you want to include. Click Generate Password to create a new random password. The strength indicator shows you how secure the generated password is. Use Copy to Clipboard to save it to your password manager or paste it directly into a website. All generation happens locally in your browser — your passwords are never sent to any server.
