Strong Passwords.
Free.
Instant.
Private.
Generate secure random passwords, passphrases, and PINs in seconds. Strength meter, bulk mode, custom settings. 100% in your browser — nothing ever stored.
Weak passwords are the #1 cause of breaches.
Most people use the same password on multiple sites. When one site is breached, every account is at risk. Strong, unique passwords fix this.
Human Passwords are Predictable
People use names, birthdays, and common words. Hackers exploit this with dictionary attacks that crack simple passwords in seconds.
True Randomness Wins
SnapHQ uses the Web Crypto API — the same cryptographic standard used in banking apps — to generate genuinely random passwords.
Length is Everything
A 16-character random password would take billions of years to crack by brute force. An 8-character password takes hours.
Never Reuse Passwords
81% of data breaches involve stolen or weak passwords. Generate a unique password for every account and store them in a password manager.
Passphrases are Memorable
A 5-word passphrase like “correct-horse-battery-staple-seven” is both highly secure and easier to remember than a random string of characters.
100% Private
Everything runs in your browser. Your passwords are never sent to any server, stored in any database, or visible to anyone but you.

What Makes a Strong Password?
A strong password has four key qualities: it’s long (16+ characters), uses a mix of character types, contains no dictionary words, and is unique to that account.
SnapHQ’s free password generator uses the Web Crypto API — the browser’s built-in cryptographic random number generator — to create passwords that are genuinely unpredictable. Not pseudo-random like Math.random(), but cryptographically secure randomness used in banking and security applications.
Our password strength meter calculates actual entropy — a mathematical measure of how difficult a password is to crack — so you can see exactly how secure your generated password is.
Password vs Passphrase — Which is Better?
Both are strong when generated correctly. Passwords use a mix of characters and are harder to remember but shorter. Passphrases use random words separated by hyphens or spaces — they’re longer, easier to type, and often more secure due to sheer length.
For accounts where you need to type the password manually (like a computer login), a passphrase is often the better choice. For accounts stored in a password manager, a 20+ character random password is ideal.
✓ Password mode — best for password managers
✓ Passphrase mode — best for memorable accounts
✓ PIN mode — best for devices and short codes
✓ Bulk mode — best for generating many at once

SnapHQ’s free password generator creates cryptographically secure random passwords, passphrases, PINs, and bulk password lists — instantly, entirely in your browser. Passwords are generated using the Web Crypto API, the same standard used in security applications. Nothing is transmitted to any server. Nothing is stored anywhere.

Generation Modes
Random Password — generates a truly random string of characters. Configure the length (8–128 characters), and choose which character types to include: uppercase letters, lowercase letters, numbers, and symbols. The strength meter shows the entropy (randomness) of your generated password in bits.
Passphrase — generates a sequence of random words separated by a chosen delimiter. Passphrases like “correct-horse-battery-staple” are long, memorable, and extremely difficult to crack — often stronger than complex passwords of the same apparent difficulty.
PIN — generates a random numeric PIN of your chosen length. For device PINs, ATM codes, and numeric security codes.
Bulk Generator — generates multiple passwords at once. Useful for creating credentials for multiple accounts, generating test data, or setting up new systems.
How to Use the Password Generator
For a random password: Set your desired length (12+ recommended, 16+ for important accounts). Check the character types you want to include — uppercase, lowercase, numbers, and symbols all increase password strength. Click Generate. Click Copy to copy to clipboard.
For a passphrase: Select Passphrase mode. Choose the number of words (4+ for strong security) and your preferred separator (hyphen, underscore, space, or none). Click Generate.
For a PIN: Select PIN mode. Enter the desired length. Click Generate.
For bulk passwords: Select Bulk mode. Set the quantity (up to 100 passwords) and your configuration. Click Generate to create all passwords at once.
What Makes This Generator Secure?
Most simple password generators use JavaScript’s
Math.random()— a pseudo-random function designed for statistical applications, not security. It’s technically predictable under certain conditions.SnapHQ uses
window.crypto.getRandomValues()— the Web Crypto API — which generates cryptographically secure random numbers using your device’s hardware entropy. This is the same standard used in TLS encryption, secure key generation, and professional security tools. The randomness cannot be predicted or reproduced.
How Strong Should Your Password Be?
Password strength is measured in bits of entropy — higher is stronger. As a general guide:
- Less than 40 bits — weak, crackable quickly
- 40–60 bits — moderate, suitable for low-risk accounts
- 60–80 bits — strong, suitable for most accounts
- 80–100+ bits — very strong, suitable for high-value accounts
A 16-character random password using uppercase, lowercase, numbers, and symbols has approximately 105 bits of entropy — effectively uncrackable with current technology.
Who Uses This Tool?
Individuals — creating strong passwords for email, banking, social media, and other personal accounts. Most people reuse weak passwords out of habit — a password generator makes it easy to use strong, unique passwords for every account.
IT professionals — generating secure credentials for new systems, user accounts, databases, and API keys.
System administrators — creating temporary passwords for new user accounts, or bulk generating credentials for account setup.
Developers — generating secure tokens, API keys, test credentials, and random strings for development and testing.
Security-conscious users — anyone who understands that password reuse and weak passwords are the #1 cause of account compromise.
Why You Need Different Passwords for Every Account
If you use the same password everywhere and one site is breached, attackers use that password to try logging into your email, bank, and every other account — a technique called credential stuffing. It’s automated, fast, and devastatingly effective.
With a password generator and a password manager (like Bitwarden, which is free), you can have a unique, strong password for every account without memorizing any of them — only your master password.
Frequently Asked Questions
Are generated passwords stored anywhere? No. Passwords are generated locally in your browser using the Web Crypto API. They are never transmitted, logged, or stored by SnapHQ or any third party.
What length password should I use? Minimum 12 characters for standard accounts. 16+ characters for email, banking, and other critical accounts. Longer is always better.
Is a passphrase more secure than a random password? A 4-word passphrase has around 51 bits of entropy. A 12-character random password with full character set has around 79 bits. For memorability combined with security, passphrases are excellent. For maximum security, use a long random password stored in a password manager.
Should I include symbols in my password? Yes, if the site allows them. Symbols increase the character set size from 62 to 94, significantly increasing entropy per character.
How do I remember all these unique passwords? Use a password manager. Bitwarden is free, open source, and highly regarded by security professionals. You only need to remember one master password — the manager handles the rest.
