Password Generator
Generate strong, random passwords with custom length, symbols, numbers, and uppercase options.
What Makes a Password Strong?
Password strength comes down to two things: length and randomness. A 12-character password drawn from letters, numbers, and symbols has approximately 475 septillion possible combinations — making it practically impossible to crack by brute force with current technology. A 16-character password raises this to numbers so large they'd take longer than the age of the universe to exhaust.
The most common password vulnerabilities are: using dictionary words or names, reusing passwords across sites, choosing short passwords, and using predictable patterns (like replacing 'a' with '@'). This generator uses the browser's built-in crypto.getRandomValues() API — the same cryptographic randomness used in secure software — ensuring every character is genuinely random, not pseudorandom.
When Should You Generate a New Password?
Creating New Accounts
Every new account deserves a unique, randomly generated password. Never reuse passwords across services — a single breach exposes all reused accounts.
After a Data Breach
When a service you use announces a breach, generate a new password immediately — not just for that service, but for any other accounts sharing the same password.
High-Security Accounts
Banking, email, password managers, and cloud storage deserve your strongest passwords — 20+ characters with full character sets. Generate one here and store it in a password manager.
API Keys & Secrets
Developers generating API keys, database passwords, encryption keys, or other application secrets benefit from cryptographically secure random strings of a specific length.
Passwords are generated entirely in your browser. Nothing is ever sent to any server.
Uses crypto.getRandomValues() — the same source used in encryption software.
Generate up to 100 passwords in one click. No waiting, no loading.
No account, no ads, no limits. Generate as many passwords as you need.
Store Your Passwords Securely
Generated strong passwords are only useful if you can remember them. A trusted password manager stores all your passwords securely, auto-fills them, and syncs across devices.
Frequently Asked Questions
Is it safe to use an online password generator?
Yes — as long as the generator runs entirely in your browser (client-side) without sending data to a server. This tool uses the browser's crypto.getRandomValues() function to generate passwords locally. You can verify this yourself by turning off your internet connection after the page loads — it will still work perfectly, because no network requests are made during generation.
How long should my password be?
For most accounts, 16 characters is considered strong. For high-value accounts like email, banking, or password managers, 20–24 characters is recommended. If the site allows it and you're storing in a password manager, there's no reason not to use 32+ characters.
What is the "Pronounceable" option?
Pronounceable passwords alternate consonants and vowels to create syllable-like patterns — for example "korimavudex" instead of "kxqmvbzrtp". They're somewhat weaker than fully random passwords of the same length, but easier to read aloud or type from memory. Use for situations where you might need to type the password on an unfamiliar device.
Should I use the same password for multiple sites?
Never. When a website suffers a data breach — and breaches happen constantly — leaked passwords are tested against every other major service in a technique called credential stuffing. Unique passwords for every account, stored in a password manager, is the single most impactful security habit you can form.
Frequently Asked Questions
How random are the generated passwords?
Passwords are generated using the Web Crypto API's crypto.getRandomValues() — the same cryptographically secure random number generator used by security software. It is not possible for us or anyone else to predict or reproduce a generated password.
Are generated passwords stored or logged anywhere?
No. Passwords are generated entirely in your browser and never transmitted anywhere. We have no access to passwords generated using this tool.
How long should my password be?
For most accounts, 16 characters provides excellent security. For high-value accounts (banking, email, password manager master password), 20+ characters is recommended. Length is the single most important factor in password strength.
Should I use symbols in my password?
Yes, if the site allows them. Symbols increase the character set size, making brute-force attacks significantly harder. The generator lets you choose which symbol sets to include.
What is a passphrase and is it more secure?
A passphrase is a sequence of random words (e.g. "correct-horse-battery-staple"). Long passphrases can be as secure as complex passwords while being easier to remember. For most people, a password manager with randomly generated passwords for every site is the best approach.
