Free Password Generator

How this random password generator works

Real randomness

Every character comes from your browser's cryptographic random generator (crypto.getRandomValues), with no bias toward any character.

Your rules

Pick a length from 6 to 50 and the character types a site accepts. Each change makes a fresh password.

Never sent, never saved

The password exists only on your screen. This page has no server step, so there is nothing to leak.

What makes a password strong

Long beats clever

Every extra character multiplies the guesses an attacker needs. Aim for 16 or more.

One password per site

When one site leaks, a reused password opens every other account that shares it.

Random, not personal

Names, dates and words from your life are the first things attackers try.

Questions

Is this password generator safe?

Yes. The password is made by your browser's cryptographic random generator. This page sends nothing and keeps nothing, so nobody else ever sees it.

How long should a password be?

At least 12 characters, and 16 or more for email, banking and anything that can reset other accounts.

How long would it take to crack a 16-character random password?

With lowercase, uppercase, numbers and symbols there are about 10^31 possible passwords. Even at a trillion guesses a second, trying them all would take hundreds of billions of years.

Should I use a different password for every site?

Yes. When one site is breached, attackers try the same email and password on other sites. A unique password keeps the damage to that one account.

How do I remember all these passwords?

You don't have to. A password manager like SyFly saves them encrypted and fills them in for you on every device.

Is it really free?

Yes, with no account and no limit. SyFly's apps and browser extension have the same generator built in.
