Generate Strong, Random Passwords
Password generator to create strong, random passwords. Random password generator with symbols, numbers, custom length. Strong password generator, secure pass...
Most people still reuse passwords across multiple accounts, and the ones they do use are short and predictable. That is a problem because the average data breach exposes millions of passwords, and if yours is among them, every account sharing that password is compromised. This password generator creates random, strong passwords quickly: you choose the length and character types, and the built-in strength meter tells you exactly how secure the result is. Everything happens in your browser; no password is ever transmitted over the internet.
Length matters more than complexity
A 20-character password with only lowercase letters (26 possible characters per position) has approximately 94 bits of entropy. A 12-character password using all four character types (94 possible characters per position) has approximately 79 bits of entropy. When possible, go longer - it is stronger than adding more character types to a shorter password.
Never reuse passwords across accounts
If you use the same password for your email, your bank, and a forum, and that forum gets breached, attackers will try the same password on your email and bank. This is called credential stuffing, and it is one of the most common ways accounts get compromised. Use this generator to create a unique password for each account.
Avoid dictionary words and common patterns
Passwords like 'Password123!' or 'LetMeIn2024' are weak because they follow predictable patterns that attackers try first. Random character sequences generated by this tool have no pattern, making them resistant to dictionary attacks and pattern-based cracking.
Use a password manager to store them
Since randomly generated passwords are impossible to memorize, use a password manager like Bitwarden, 1Password, or KeePass to store them securely. You only need to remember one master password; the manager handles the rest.
All generation happens in your browser
When you click Generate, JavaScript running inside your web browser creates the password. The code uses the browser's built-in Math.random() function combined with a Fisher-Yates shuffle to produce unpredictable results. The generated password is never sent to any server, never logged, and never stored.
The strength meter analyzes your configuration
The strength indicator evaluates both the length of your password and the variety of character types you have enabled. It rates passwords on a four-point scale from Weak to Very Strong based on the estimated entropy of your chosen configuration. A password rated Very Strong would take billions of years to crack using current hardware.
Password history is temporary and local
The tool shows your ten most recently generated passwords for convenience, but this history exists only in your browser's memory. Closing the tab, refreshing the page, or navigating away clears the history completely. No password is ever written to disk or transmitted anywhere.
