Facebook – Why Facebook Accepts More Than One Password

facebook

With Facebook login, my password had a form of uppercase letters, lowercase letter and numbers. Not strong, but it did the job. For example

hunTer2

Recently, I was told by an acquaintance that I could do these as well

HunTer2
HUNtER2

I have tried other combinations but they do not seem to work. Is there a reason Facebook allows these alternative passwords?

It's because of caps lock key on/off to prevent double entering password.

Per http://www.zdnet.com/blog/facebook/facebook-passwords-are-not-case-sensitive-update/3612

Facebook actually accepts three forms of your password:

  1. Your original password.

  2. Your original password with the first letter capitalized. This is only for mobile devices, which sometimes capitalize the first character of a word.

  3. Your original password with the case reversed, for those with a caps lock key on.

The third case is the one I stumbled upon today. Wolens told me Facebook has had this implemented “for a while” although he couldn’t say for exactly how long. He also noted that Facebook doesn’t believe this impact the security of the user’s passwords, since the characters are still unique, just flipped.
