login facebook using 3 different passwords

Did you know that your Facebook account can be logged in with 3 different passwords ? Yes, this is true. Facebook offers you to access or sign-in your account easily ( But don’t ever think that  Facebook has a bug or a serious vulnerability ). Facebook’s acceptable passwords are :

1. Main Password

Your default Facebook password that you created during the sign-up process is:

                              "yourAccountPassword"

 2. Case Toggled Password

Here you can see that all the case of the password is toggled.

                       "YOURaCCOUNTpASSWORD"

 3. 1st Capitalized Letter

In this case first letter of your account password is capitalized and the remaining are same. This is because mobile devices are used to do the first letter capitalized.

                            "YourAccountPassword"

Reason Behind It
Actually Facebook provide us this option to avoid typing hazards in mobile. That’s why this option is only works when you’re using Facebook from mobile.
