Regular Tumblr users will be happy to hear that the service has now added two-step authentication to keep your accounts more secure. Wherever its available we'd always recommend using two-step authentication for that added layer of protection on your accounts.
Tumblr's can be turned on in your account settings, and ties your login to your cell phone number – using SMS messages – and lets you make use of an app such as Google Authenticator to generate the unique login codes. The folks at TechCrunch reported a little jankyness getting set up, but persevere and everything should work out just fine in the end.
If you're a Tumblr user, fire up your account and take a look. Is this something you've been longing for?
