Frequently Asked Questions
What is a Passphrase?
It's a password made of multiple random words instead of gibberish characters. It's much easier to remember but mathematically very hard to crack(´∀｀)
Is the leak check really safe?
Absolutely! The tool hashes your password locally and only sends the first 5 characters of the hash to the API. It's impossible for anyone to know the full password.
Can I use it on my phone?
Yes! You can even generate a QR code for the password to easily scan it with your phone( ˘ω˘ )
