Free Strong Password Generator

Create secure, random passwords in seconds. Our password generator lets you customize length and character types to build strong, unique passwords for any account.

How It Works

This password generator creates cryptographically random passwords using your browser's built-in secure random number generator - the same technology that secures HTTPS connections.

Here's the generation process:

Build character pool: Based on your selections, it combines character sets - lowercase (26 chars), uppercase (26), numbers (10), and symbols (32).
Ensure coverage: The generator guarantees at least one character from each selected type, preventing passwords that accidentally lack diversity.
Fill randomly: Using crypto.getRandomValues(), it selects random characters from the pool until reaching your desired length.
Shuffle thoroughly: The final password is shuffled to ensure the guaranteed characters aren't predictable (like always having a number at the end).

Unlike many online generators, this tool runs entirely in your browser. Generated passwords never leave your device - they're not sent to any server or stored anywhere.

When You'd Actually Use This

Setting Up New Accounts

Generate a unique, strong password for every new signup. Never reuse passwords across sites.

Replacing Compromised Passwords

After a data breach notification, quickly generate a replacement password that's completely unrelated to the old one.

Populating Password Managers

Bulk-generate strong passwords when migrating to a password manager or doing a security overhaul of all your accounts.

Creating Service Accounts

Generate passwords for API keys, database connections, and other machine-to-machine authentication that humans won't type.

Temporary Access Credentials

Create one-time passwords for contractors, temporary employees, or shared access that can be changed later.

Security Policy Compliance

Meet organizational requirements for minimum length and character complexity without thinking about it.

What to Know Before Using

You must save the generated password

Once you navigate away or refresh, the password is gone forever. Always copy it to a password manager or secure storage immediately. There's no 'recover password' feature.

Longer isn't always better for usability

A 64-character password is incredibly secure but painful to paste on devices without clipboard access. For most uses, 16-20 characters provides excellent security with reasonable usability.

Some sites have weird password limits

Surprisingly, some services still limit passwords to 16 characters or ban certain symbols. You might need to regenerate if your password gets rejected.

Exclude ambiguous characters for manual entry

If you'll ever need to type the password (not just paste), enable 'exclude ambiguous' to avoid confusing characters like I/l/1 and O/0.

Symbols can cause issues in some contexts

Passwords with special characters sometimes break in command-line tools, URLs, or legacy systems. Consider your use case before including all symbol types.

Common Questions

How long should my generated password be?

For most accounts, 16 characters provides excellent security. For high-value targets (email, banking, password manager), use 20-24 characters. For service accounts that never get typed, 32+ characters is reasonable.

Should I include all character types?

Yes for maximum security, but there's a tradeoff. A 20-character lowercase-only password (about 94 bits) is stronger than a 12-character mixed password (about 78 bits) and easier to type. Prioritize length first.

Is it safe to use an online password generator?

This generator runs entirely in your browser using secure random number generation - no data leaves your device. Be cautious of generators that might log or transmit your passwords.

Can I use these passwords for WiFi networks?

Yes, but consider excluding ambiguous characters since you'll likely need to type them on multiple devices. A 20-character password without I/l/1/O/0 is still extremely secure.

What if the generator creates a password I can't pronounce?

That's actually ideal for security! Unpronounceable passwords are less likely to be modified or remembered (which tempts reuse). Save it in a password manager and never try to memorize it.

How often should I regenerate passwords?

Only when necessary: after a breach, if you suspect compromise, or when setting up new accounts. Modern security guidance discourages routine rotation of strong, unique passwords.

Can I generate multiple passwords at once?

Yes! The 'Generate 5' button creates multiple options. This is useful when you need several passwords (like setting up multiple accounts) or want to pick one that works with a site's specific requirements.
