Strong Password Generator

Generate a strong, random password in your browser. Pick the length and character sets and it builds one using your device's cryptographically secure random generator. Nothing is sent over the network or stored — close the tab and it's gone.

Need more than the free basics? Generating a strong password is step one — the hard part is storing and sharing them safely across a team. That's what a zero-knowledge password manager like Passpack does: encrypted team vaults at a low per-user price.

What makes a password strong

Length beats complexity: a long password drawn from a big character set is exponentially harder to crack. Aim for at least 16 characters, mix in symbols and numbers, and — crucially — use a different password for every account. That last rule is impossible to keep in your head, which is exactly why a password manager exists: you remember one master password, it remembers the rest.

Frequently asked questions

Is this password generator safe?

Yes. It runs entirely in your browser using the Web Crypto API (a cryptographically secure random generator). Nothing is transmitted, logged or stored — the password only exists in your tab.

How long should my password be?

At least 16 characters; 20+ is better for important accounts. Length matters more than swapping letters for symbols, though using multiple character sets helps too.

Why use a different password everywhere?

If one site is breached, reused passwords let attackers into your other accounts. Unique passwords contain the damage to a single account.

How do I remember all these passwords?

You don't — that's what a password manager is for. You memorise one master password and it securely stores and fills the rest. For teams, Passpack adds shared encrypted vaults.
