Finally! Twitter has added two-factor authentication, which requires a second check (a verification code sent to your phone) when you sign into the service from an unknown device. This is a much-needed feature for online accounts to prevent hackers from taking over your account (and we’ve seen that happen a lot, on Twitter especially). Here’s how to get this set up and the other places you need to turn on two-factor authentication.
For Twitter, log into your account, click on the gear icon in the navigation bar, and choose Settings (or go to https://twitter.com/settings/account). Next to the Account security setting, check “Require a verification code when I sign in.” If that’s grayed out, you’ll first need to add a phone to your account and then go back to the Settings to turn on two-factor authentication. Learn more from Twitter’s announcement.
Where else should you turn on this extra security feature? In a word, everywhere. Most importantly:
- Your email account(s). See instructions for Gmail.
- All financial service accounts (bank, investments, etc.)
- Password-management sites, such as LastPass
- Online storage service providers, including Dropbox
- Microsoft(used for your SkyDrive, Office Web, Xbox, Windows 8 PC login, and more)
- Other social media sites, such as Facebook
- WordPress, if you have a WP blog (see my post on ITworld), other webhosting service, and domain name service providers
