I can see where Android OS is coming from, but I understand now that you basically are pulling information like most sites do. I don't know if any of you have heard of OpenID. I personally would never use it. If someone DID hack my Twitter or Facebook account, they would have access to all of the sites using OpenID. That's why I never signed up with them in the first place.
But I can see the measures of security when it comes to social media integration. I'm not seeing too many sites using OpenID like I used to, which tells me it's fading in a way. I personally agree with integrating Facebook to pull basic information when signing up for a site, and I wouldn't mind doing it.
However, I have disabled it on my forums because users didn't want to show that in their timeline. I explained to them that you can make posts disabled or private posted by the application, but others thought it wasn't so secure, and not many we're using it, so I disabled it altogether.
Personally, when it comes to security, I am not all the best at it. All of my passwords are almost the exact same as one another, and if a site requires more I just throw it on the end. I store my passwords online, which isn't so smart. My bank account passwords are all the same, etc., etc. It's just difficult for me to remember a whole bunch of different passwords if I used them. I don't like writing them down or saving them in a spreadsheet either.
I may use integration again in the future, but for now I have it disabled.
