More words increase security but may reduce memorability.
Choose a separator that’s easy to type.

How to Use

01

Select Word Count

Choose how many words you want in your passphrase. More words equal higher security.

02

Choose a Separator

Select a character to separate your words, like a hyphen, underscore, or space, to make it readable.

03

Add Extra Security

Optionally toggle capitalization, numbers, or symbols to meet specific complexity requirements.

Frequently Asked Questions

Why use a passphrase instead of a password?

Passphrases are often longer than traditional passwords but much easier to remember. Because of their length, they are extremely difficult for computers to crack via brute force.

Are these words truly random?

Yes. We use the cryptographically secure `crypto.getRandomValues` API in your browser to ensure that the word selection is unpredictable.

What is 'entropy' in the context of passphrases?

Entropy measures the unpredictability of your passphrase. A higher entropy value (in bits) means there are more possible combinations, making it exponentially harder to guess.
