Generate a strong secret passphrase

For anyone who needs a memorable credential without personally choosing words that may be easy to predict.

Draw a secret phrase using cryptographic randomness and receive a strong, readable combination that matches your selected settings.

How to use

Enter the number of words you want, from 4 to 12, in the field provided by the interface.
Run the generation to get a passphrase built with cryptographic randomness.
Read the produced phrase and check that it contains the number of words you requested.
Copy the passphrase and keep it in a password manager or another safe place.
Erase the result to generate another phrase without leaving the previous one visible.

Example

With the sample input 6, the tool builds a six-word passphrase. Look mainly at how readable the phrase is and at the number of words you get; you can then memorise it or store it before leaving the page, but avoid writing it in a public note.

Input

Output

marbre-source-dune-volcan-vallee-brise

Limits and formats

A passphrase is only strong if it stays private and is not reused elsewhere.
The number of words must stay within the range shown by the interface.
The generator does not check whether the phrase already appears in a published breach.
Copy the phrase before erasing, because the result is not stored anywhere else.
Do not paste the phrase into a chat or email you cannot secure.

Where processing happens

The passphrase is generated inside your browser. The random draw happens on your device, and nothing is sent or saved remotely. You can create a secret without an account or a file upload.

Frequently asked questions

What does cryptographic randomness mean?

It means the words are drawn using a randomness source intended for security, not an ordinary generator. The goal is to make the phrase hard to guess by simple trial and error.

How many words should I choose?

The interface accepts 4 to 12 words. A longer phrase usually offers more combinations, but it is also harder to memorise, so choose according to how you plan to use it.

Can I reuse the same passphrase on several sites?

It is better not to reuse a passphrase across different services. If one site is compromised, every other account protected by the same phrase also becomes exposed.
