Random Password Generator
Use our random password generator to create secure passwords fast. Adjust length, include letters, numbers, and symbols, then copy in one click.
Generate the Password
What this tool does
This is the password generator with the dials exposed. You set the length, anywhere from 4 to 32 characters, and choose exactly which kinds of characters go in: uppercase, lowercase, numbers, and symbols. It builds a random password to match, ready to copy. If you would rather not fiddle with the options, the strong password generator keeps it to a single length slider.
How to use it
- Drag the length slider to the number of characters you want.
- Tick the character types to include: uppercase, lowercase, numbers, and symbols. Leave on as many as you can.
- Press refresh for a new password, and copy when you have one you like.
How it works
The tool builds your password by pulling characters at random from the sets you switched on, and assembling them to the length you set. Turn symbols off and none appear; turn numbers on and they join the pool. It all happens in your browser, so nothing you generate is sent over the internet or stored, and the strength indicator updates to reflect the choices you have made.
Why the control is useful
The same rule from password security applies here: length does more for strength than anything else, so the single best move is to push the slider higher. Every character type you switch off shrinks the pool the password is drawn from and makes it a little weaker, so the general advice is to keep them all on.
So why offer the switches at all? Because the real world is fussy. Some sites quietly reject certain symbols, or cap which characters they accept, and a password full of symbols is no use if the site bounces it. Being able to turn symbols off, or build a digits-and-letters-only password, lets you match those rules without giving up length. Use the control to fit the site, then make back any lost strength by adding a few more characters. You can check the result's strength if you want to see where it lands, and the bulk generator makes many at once.
Questions people ask
What length should I choose?
At least 12, and 16 or more for important accounts. Length helps more than any character setting, so when in doubt, make it longer.
Should I include all character types?
Generally yes. Each type you include widens the pool the password is drawn from. Only turn one off if a site refuses to accept it.
Why would I turn a character type off?
To satisfy a site that rejects certain symbols or limits which characters it allows. Turn off what the site will not take, then add a couple of characters to keep the password strong.
Is it safe to generate a password here?
Yes. The password is built in your browser and is not sent anywhere or saved, so it stays on your device.
