Facebook Account password mystery

In my previous post, I explained how we can play with Google account username. In this post, I will let you know something about Facebook account.

As Google ignores periods in username, Facebook ignores the "CAPITAL CASE" letters in password.

Means if your Facebook password is abcd, you can also use Abcd or ABcd or ABCD or any combination of small and capital letters.


This is a bit surprising because in 99.99% cases, we think that passwords are case sensitive (& it should be due to the security reason).

But Facebook has a different logic.When we use a desktop or Laptop, we can easily identify that our "CAPS" lock is ON or OFF & we always take care about it.
But when we use our android device or iphone etc & try to enter any string then most of the time, by default First letter will be "CAPITAL CASE" letter & use may experience "Invalid Password" error.

To get rid off this situation, Facebook has started to ignore "CAPITAL CASE" letters or vice versa to enhance the user experience of their mobile app.

Now, when you will use your Facebook app, no need to worry about Capital/Small case letters. Just enter your password & enjoy the Facebook.

Google Account login mystery



1. If your username contains a dot (.), then you can also login to your google account by skipping that dot.
E.g: abc.xyz can be accessible by abcxyz. (but account login will be displayed as abc.xyz)

2. If your username doesn't contains any dot (.), you can split your username by placing any number of dots (.) & try to login to your account.

E.g: if my login id is abcxyz then I can use either abc.xyz or abc.x.y.z or abc...xyz etc. (whatever combination you want).

This is because Google has started to ignore periods.

So, you can take advantage by creating several Email Alias of your single Google Account & use them for different purpose.
E.g: abcxyz for your personal use, abc.xyz for friends etc.

I have tried all above test cases & works fine for me. There may be some exceptions E.g: If two different people created two different login as abcxyz & abc.xyz etc. I haven't tried this but I hope this will also work.

This is (may be) just like the Email Alias in outlook.com (previous hotmail.com).

Have Fun !!!!!!!!
