12 character password generator
It is already set to 12 characters with every type turned on. Copy the one you see or generate another with one click.

Added to the sets you picked.
Each word comes from a list of 7,773 common English words and adds 12.9 bits. It is easy to remember and hard to guess.
A PIN is only secure if the service limits the number of attempts. For online accounts, use a long password.
From 1 to 50
It is not sent anywhere. It is analyzed in your browser.
This is an upper-bound estimate: it does not know every word in every language or the passwords that have leaked. A phrase made of common words is worth much less than it looks.
Best practices
- Use a password manager so you do not have to remember them.
- Turn on two-step verification on important accounts.
- Do not reuse the same password on different sites.
How to use it
- Pick the type: random password, passphrase made of words, or numeric PIN.
- Set the length and the characters you want to use. The password regenerates on its own with every change.
- Check the strength: we show the bits of entropy and the estimated time it would take to guess it.
- Copy the password with one click. If you generated several, you can copy them all or download them.
- Save it in a password manager: it is not kept here.
Frequently asked questions
Is a 12 character password secure?
It is a good balance between security and convenience. It beats 8 characters, but for critical accounts 16 is better. Strength is measured in bits and shown below the result.
How do I copy the password?
Select “Copy”. It goes to your clipboard and is not recorded anywhere. If you prefer, you can download it as a text file or generate it again.
Can I remove the symbols?
Yes. Turn off “Symbols” in the options and the password is recalculated. Keep in mind that every character type you turn off lowers the entropy and the final strength.
Twelve characters, a reasonable middle ground
A random 12 character password with uppercase, lowercase, numbers, and symbols has far more combinations than an 8 character one. It is still easy to paste into a password manager and works on almost any site.
When to go longer
For email, banking, and work accounts, 16 characters or more is recommended. If the site allows passphrases, five random words are also very strong and easier to remember. Try the 16 character password or go back to the full tool to choose the length by hand.
