Although I applaud the effort to protect users, I can’t be the only one eyeing this development with some suspicion. Currently, Twitter requires each account to have a unique email address. What happens if this requirement is extended to cell phone numbers? Those of us with multiple Twitter accounts will be hard pressed to maintain that many cell phones, so let’s hope they don’t go that far.

After a series of high profile hacks, Twitter is finally getting serious about log-in security with a new feature that will require users to enter an extra pin code when using non-familiar devices.
The feature, known as “two-factor” authentication, is already used by companies like Google and Apple and works by sending a pin code via text message to a user’s cell phone. Twitter has details and a tutorial video here.
The decision to add an extra security feature comes after hackers have repeatedly gained control of high profile Twitter feeds. The most prominent example occurred last month when hackers used the Associated Press’s account to say bombs had injured President Obama. The fake tweet roiled financial markets and led to calls for Twitter to improve its security features.
