Strong Password Generator: Create Secure Passwords Instantly
Weak passwords are the leading cause of account breaches. Using "password123" or your pet's name — even on low-stakes accounts — puts your other accounts at risk through credential stuffing. A strong password generator creates cryptographically random passwords that take millions of years to crack.

Password strength is determined by entropy — the measure of unpredictability. A strong password is: at least 16 characters long, uses all character types (upper, lower, numbers, symbols), has no recognizable words or patterns, and is unique to each account. Using the same strong password across multiple sites still leaves you vulnerable to database breaches.
How Formly's Password Generator Works
The password generator uses your browser's cryptographically secure random number generator (window.crypto.getRandomValues) — the same standard used by security software. Crucially, the generated passwords are never sent to any server. Everything happens locally in your browser.
Password Policies: Character Requirements
Different systems have different password requirements. Formly's generator lets you: set length (8–64 characters), include/exclude uppercase letters, lowercase letters, numbers, and special symbols. You can also exclude ambiguous characters (O, 0, l, 1) for easier reading.

Password Manager Compatibility
Generated passwords are designed to work with all major password managers: 1Password, Bitwarden, LastPass, Dashlane, and Apple Keychain. The best practice is: generate a strong password with this tool, immediately save it in your password manager, and never type it again.
Passphrase vs Random Password
Passphrases (e.g., "correct-horse-battery-staple") are long and memorable. Random passwords are shorter but maximally unguessable. For accounts you need to type regularly without a password manager, a passphrase may be more practical. For most accounts, a random 20+ character password in a password manager is optimal.
Password Security Best Practices
Beyond strong passwords: enable two-factor authentication (2FA) on all important accounts, use a password manager, never reuse passwords, don't share passwords via email or text, and change passwords immediately after a known data breach. Check haveibeenpwned.com regularly to see if your email has been in a breach.
Frequently Asked Questions
Are generated passwords stored anywhere?⌄
No. Passwords are generated entirely in your browser using the Web Crypto API and never leave your device.
How long should my password be?⌄
Security experts recommend a minimum of 16 characters for most accounts, and 20+ for high-value accounts like email, banking, and password managers.
Is a 16-character password secure enough?⌄
A 16-character random password with mixed character types would take billions of years to brute-force with current technology.
Can I generate multiple passwords at once?⌄
Yes. Generate up to 10 passwords simultaneously to choose the one easiest to type or match specific requirements.
Is the generator truly random?⌄
Yes. It uses window.crypto.getRandomValues, which provides cryptographically secure randomness — the same standard used in SSL/TLS encryption.
