Dropbox to enable 2 factor authentication in the next few days.

This is great news! Relying more and more on cloud services, I just recently enabled Google’s 2 step verification.Now Dropbox is joining the party by announcing their own 2 step verification in their forums.

It can be activated by downloading the latest forum build of their client software.

You can receive the authentication codes needed for logging in with unknown/new computers or web browsers either via SMS or the following existing authenticator apps for mobile devices (which can generate valid codes even if offline – very useful if you are traveling).

• Google Authenticator(Android/iPhone/BlackBerry)
• Amazon AWS MFA(Android)
• Authenticator (Windows Phone 7)

And yes, there is a client available for Windows Phone!
