Use the Password Generator in three steps

01

Choose a length

Longer passwords are generally harder to guess.

02

Select character types

Include uppercase letters, numbers, and symbols when the website allows them.

03

Generate and store

Copy the password into a trusted password manager.

Length matters

A long unique password is usually more valuable than a short complicated one. Many people choose at least 16 characters for important accounts.

Use a password manager

Do not reuse generated passwords across services. A reputable password manager can store a different password for every account.

Password Generator FAQ

Are generated passwords sent anywhere?

No. Password generation uses your browser’s local cryptographic API.

Does this tool save my password?

No. The password is not saved by the tool, so store it safely before leaving the page.

How is randomness generated?

The tool uses the browser Crypto API rather than Math.random, providing randomness designed for security-sensitive browser features.

How long should a strong password be?

Sixteen or more random characters is a practical choice for many accounts, provided the service accepts that length.

Should every account have a different password?

Yes. Unique passwords prevent a password exposed by one service from unlocking your other accounts.

Why does a website reject the generated password?

Some websites limit length or allow only certain symbols. Adjust the length or disable symbols, then generate another password.
