In late May, Twitter finally launched two-step verification. The tool was introduced as a way to hopefully cut down on the number of high profile Twitter account hacks that left many celebrities and brands dealing with minor PR disasters. Now Twitter has updated its verification process to be even more secure.

Twitter announced today that users can now use their mobile apps to login into their accounts via two-step verification. SMS-based login verification will still be available, but the mobile app provides another level of security. Here are all the features that come with two-step verification on the mobile app:

No phone number required: By using push messaging and in-application approvals, you no longer need to provide your phone number to use login verification. If you manage multiple Twitter accounts, but only have one phone number, you can now opt all of them into login verification.

Broader international support: Now, all you need is an Internet connection and one of our supported apps to enroll in login verification. Login verification via SMS has been available through supported mobile carriers across the world, but that didn’t cover everybody.

“My phone fell in the ocean!”: Backup codes generated in the application can be written down, stored in a safe place, and used to access your account on twitter.com even if you lose your phone.

More context: When a login request is made, you will see browser details and approximate location in the app. If you receive an approval request from halfway across the world, you may be getting phished. Review this page for more information on keeping your account secure.

So, how do you enable all of these new features? Twitter says you just need to open the app and turn on Login Verification on the Settings page under security. With it enabled, the application will handle all sign in approvals.

As an added bonus, Twitter is also introducing some refinements to search and photos in its official mobile app alongside the two-step verification features. First, the search menu will now include social context as part of its autocomplete suggestions. Secondly, you can now view an entire photo gallery when looking through photos in search.

You can download the latest iOS and Android apps from the App Store and Google Play.
