If someone else used a password, and it was hacked, then you are at great risk of being hacked yourself. To learn more, please google "hacked password hash database".
We collected tens of millions of passwords that are, unfortunately, available on Internet, and we put them all into one fat App.
If you wonder, 'Why is this App so big (80 MB)?', then the answer will please you: This App does NOT have access to Internet, SO WE COULD NOT STEAL YOUR PASSWORD. YOU DO NOT HAVE TO TRUST US - CHECK THE PERMISSIONS OF THIS APP. IT HAS NONE.
Tens of millions of known cracked passwords have been included with this App, so you can check inside your phone, SECURELY, if your password is good to use.
This App does not measure the quality of your password (if you would like this feature too, please say so in reviews, and we might add it).
'Bad Passwords' App only tells you if the password was cracked, and if so, how many people using that password have been hacked.
One lemon - there is 1 person hacked with that password. Two lemons - there are at least 2 persons hacked with that password. Three lemons - there are at least 10 persons hacked with that password. Four lemons - there are at least 100 persons hacked with that password. Five lemons - there are at least 1000 persons hacked with that password. Six lemons - there are at least 10000 persons hacked with that password.
ORANGE - No person was hacked using that password, yet - but you can be the first one, if your password is not strong enough.
