Safe

Is your password safe? Safe will check the password strength for you.

How it works

Safe will check if the password has a simple pattern, for instance:

1. password is in the order on your QWERT keyboards.
2. password is simple alphabet step by step, such as: abcd, 1357

Safe will check if the password is a common used password. Many thanks to Mark Burnett for the great work on 10000 Top Passwords.

Safe will check if the password has mixed number, alphabet, marks.
