Twitter has been working on integrating a two-factor authentication system to the service’s sign in process in the last couple of months. It’s main aim is to provide users of the company’s service with additional options to improve their account security.
Yesterday, Twitter announced that it began to roll out the login verification feature to all users of the service.
If you enable two-factor authentication, you are asked to enter a second code during sign in to Twitter. An attacker trying to get access to the account would have to know both the username and password and the second code. Since it is generated dynamically whenever you try to sign in, it is necessary to get hold of your mobile phone as the code is automatically send to your phone via SMS.
Setting up login verification
The first thing that you may need to do is verify your account’s email address and phone number. This is a prerequisite before you are allowed to enable the login verification feature.
If you have done so already, skip the paragraph below.
- Verify a phone number: To verify a mobile phone number open the Mobile page on Twitter after you have signed in to the service. If you have troubles doing so check out Twitter’s support page that walks you through the process.
- Verify your email address: You also need to verify your email address if you have not done so already. You do that on the Account’s settings page.
Once you have verified both your mobile phone and email address you are ready to proceed.
- Open the account settings page on Twitter again.
- Locate the Account security setting on the page.
- Check the “Require a verification code when I sign in” box next to it. You can only do so if you have verified your email and phone.
- Twitter will send a test message to your phone. You need to confirm on the page that you have received it.
- Enter your Twitter password afterwards to complete the setup.
Twitter has published a video that details how you set login verification up. Use it as reference if you are stuck in the process.
When you sign in to Twitter you are asked to enter a six digit code after you have entered your username and password. The code is send to your phone via SMS, so make sure you have your phone around when you log in.
- Third party applications may not support the new feature. To continue using them, generate temporary passwords on Twitter’s application page.
- You can check the list of supported mobile carriers on this support page. If your country or provider is not listed, you cannot verify your phone right now. This is for instance the case for users from France and Germany.
- It is still important to follow security guidelines after enabling login verification on Twitter. This means, it is still recommended to select a secure account password, make sure you do not click on questionable links and that your computer’s operating system and software is kept up to date with the latest security patches and updates.
