Security is a big deal for users of all sorts of services and applications online. When those services are blogging and photo platforms like Facebook, tumblr, and others, security is even more important since a hacker could gain access to information and images that could be harmful to the user. Tumblr has announced that it is introducing a new form of authentication.
Users of Tumblr can now choose to activate two-factor authentication for their accounts. With the two-factor authentication activated, before you can access your account you need a password you type in and a code sent to your mobile device. If a hacker learns your password somehow, they will not be able to access your account without the ability to get the cell phone auth code.
If you aren't worried about hackers getting into your account and writing embarrassing things or stealing your photos, you can leave the new authentication method off. The downside is if you lose your mobile or leave it somewhere, you won't be able to get into your Tumblr account.
