About the Password Gen Tool
Human-chosen passwords are predictable in ways that automated cracking exploits ruthlessly. Substituting 3 for e and appending a digit does not help — those patterns are in every wordlist. Genuine randomness is the only reliable defence, and people are demonstrably bad at producing it.
This generator uses the browser’s cryptographic random number generator, the same source used for security-critical operations, rather than ordinary pseudo-randomness. Generation happens entirely on your device and nothing is transmitted or logged.
How to Use Password Gen
- Choose your password length. Sixteen characters or more is a sensible minimum.
- Select which character sets to include: uppercase, lowercase, digits, and symbols.
- Press Generate to produce a random password.
- Copy it straight into your password manager.
When to Use This Tool
- Creating a unique password for a new account
- Replacing a reused password after a breach notification
- Generating strong credentials for a database or service account
- Producing API keys or shared secrets for development
- Setting up passwords for family or team accounts
Things Worth Knowing
- Length matters more than complexity. A long password from a large character set is exponentially harder to crack.
- Never reuse a password across sites. A breach at one service then compromises all of them.
- Use a password manager — remembering unique random passwords for every account is not realistic.

Frequently Asked Questions
How long should a password be?
At least 16 characters for important accounts. Each additional character multiplies the search space, so length delivers far more security than adding one more symbol to a short password.
Is generating passwords in a browser safe?
This generator uses crypto.getRandomValues, the browser’s cryptographically secure random source, and runs entirely on your device with nothing sent anywhere. That is as safe as a local password manager’s generator.
Should I include symbols?
They increase the character set and therefore strength, but some systems reject certain symbols. If a site refuses them, compensate with extra length — that is more effective anyway.
How do I remember all these passwords?
You do not. Use a password manager and memorise one strong master passphrase. That is the only approach that scales to the number of accounts people actually have.
