Finally by using its SMS service Twitter now allows users to set up two-factor authentication for their accounts which when turned on requires user to enter special code send by Twitter to phone to logon to the site apart from entering the password. Twitter calling this security feature as login verification. This feature is still rolling out and not available to some cell phone carriers, you can find this below ‘password reset’ option in account settings if available to you.
Enabling Login Verification for Twitter account
1. Sign into your Twitter account using your username and password.
2. Visit Settings page.
3. Add your mobile phone: For Twitter to send Text messages first you need to activate your mobile phone, for that under Account Security setting click on “Add phone” link and enter your mobile number, select your carrier and click on ‘Activate phone’.
4. On next step you need to send SMS to particular number displayed on screen then Twitter receives it and sends confirmation message about your activation of mobile.
5. Now select ‘Require a verification code when I sign in’
Cons or problems with Twitter login verification
You need to enter code send my Twitter every time when you login, that’s annoying. And no trusted PC option which Google and Dropbox offers. Even more there is no “resend code” again option when you don’t receive the code. Though this security feature in early-stage I’d have used two-step login verification if those above mentioned annoyances were addressed.
Disable or deactivate Twitter login verification
1. Visit Twitter account Settings page.
2. Uncheck “Require verification code when I sign in”, re-enter your password to save changes to your account.
