How to generate a 16 character password
Open the tool
The length is already set to 16 characters, so you can generate straight away or adjust it if a site needs something different.
Pick your character types
Keep uppercase, lowercase, digits and symbols on for maximum strength, or trim them to match a site's rules.
Generate and copy
Generate the 16 character password and copy it in one tap, then paste it into the signup form or your password manager.
Why 16 characters is a good length
Sixteen characters is long enough to make brute-force guessing impractical for normal accounts while still being a length most websites accept. When you combine that length with mixed character types, the result is a password that is very hard to guess and easy to use.
Each 16 character password here is built from random values produced by crypto.getRandomValues in your browser. The passwords are generated locally and are never uploaded or stored by the tool, and there is no account to create.
Frequently asked questions
Is a 16 character password strong enough?
For everyday accounts, yes. A random 16-character password with mixed character types is very hard to guess. For highly sensitive accounts you can go longer.
Can I change the length away from 16?
Yes. The tool is preset to 16 characters, but you can raise or lower the length to fit a site's requirements.
Are the passwords random?
Yes. They are generated with the browser's cryptographically secure random source, so there are no predictable patterns.
Is anything uploaded?
No. The 16 character password is created locally in your browser and is never sent or stored by the tool.
What if a site rejects my password?
Some sites limit length or ban certain symbols. Turn off symbols or adjust the length, then generate again.
