How to Create a Strong Password

  1. 1

    Set Your Length

    Drag the slider to your desired length. We recommend 16+ characters for most accounts, 20+ for critical accounts like email or banking.

  2. 2

    Choose Character Sets

    Enable uppercase, lowercase, numbers, and symbols. More character types = exponentially more combinations = harder to crack.

  3. 3

    Generate & Copy

    Click Generate, then copy with one click. Generate multiple passwords at once for batch account setup.

Why Use a Password Manager?

The biggest security risk isn't password strength — it's password reuse. When any website suffers a data breach, attackers test stolen credentials on every major site (credential stuffing). A password manager lets you use a unique, strong password for every account without memorizing them. Popular free options include Bitwarden (open-source) and KeePassXC (offline). Our generator pairs perfectly with any password manager.

Frequently Asked Questions

Is this password generator truly random?

Yes. The generator uses the Web Crypto API's crypto.getRandomValues() function — the same cryptographic randomness used by password managers and security software. This is statistically indistinguishable from true randomness and far superior to Math.random(), which is not cryptographically secure.

Can SnapTool see the passwords I generate?

No. The password generation runs entirely in your browser using JavaScript. No data is sent to any server, logged, or stored anywhere. Once you close the tab, the passwords are gone forever.

How long should a password be?

Security experts recommend at least 12–16 characters for most accounts. For high-value accounts (email, banking, password manager master password), use 20+ characters. Our tool defaults to 16 characters — a good balance of security and usability.

Should I include symbols in my password?

Yes, whenever the website allows them. Adding symbols significantly increases the number of possible password combinations. A 16-character password with all character types has over 10^30 possible combinations — making brute-force attacks practically impossible.

What is the best way to store passwords?

Use a reputable password manager such as Bitwarden (free, open-source), 1Password, or Dashlane. Never reuse passwords across sites, and never store them in plain text or a browser's autofill without a master password. Generate a unique password for every account.
