Facebook is an addictive network. The more you spend time on it, the more you like it. As of now, if I would say you can login with multiple usernames in facebook, then it won’t look a big deal to you because you can have more than one login username for facebook. You can even login with your mobile phone number, if you’ve got it verified. You can even login with your facebook profile custom username ( the one you use at https://www.facebook.com/USERNAME). But I am going a step further and telling you that there are two passwords to your account other than the one you use, then this might sound as a breach in security. But when you will get to know the passwords, then you’ll think that this is not a breach but it is an intelligent feature which can be helpful.
Okay for now, let me give you a hint. The other two passwords can be formed from you existing password by just changing the cases of alphabets.
Yes have a look at the image below:
For example, if your current password on Facebook is proudIndi@N!, then you can even login by converting all the uppercase alphabets to lowercase (and vice-versa) and then login with the newly created password string i.e. –PROUDiNDI@n!
There’s one more toggling which will allow you to login which by changing the case of the first alphabet only i.e if your password’s first case is lower then change it to uppercase and vice versa– i.e ProudIndi@N! would also allow you login. All the curious reader can try it now at facebook.com/login.php.
Main Reason Behind
This is not a bug in the network but it is done due to a case study made behind wrong typing of passowrds by Facebook. There is nothing like multiple passwords which exist on Facebook, it is just provided for the help of users so that if in case at anytime, the password entered differs due to pressing of Caps Lock then it should allow user to login.you can log into Facebook using multiple usernames as well.
I also researched about it a bit and read an interesting point at Stack Exchange thread where the reason was given by Facebook officials.
According to Facebook:
We accept three forms of the user’s password to help overcome the most common reasons that authentic logins are rejected. In addition to the original password, we also accept the password if a user inadvertently has caps lock enabled or their mobile device automatically capitalizes the first character of the password.
So if in case your password differs by only caps lock position, then it won’t prompt you to login again and increasing load on server but simply allow you to login and enjoy the ride!
