Twitter

Use a strong password

As with everything, make sure you use a strong password for both your Twitter account and the email account associated with it.

Use Two-Factor Authentication

While not ideal, Twitter does not yet support using authorization apps such as Authenticator, Authy, or physical Yubikeys. In the meantime, the next best thing is “login verification” which prompts you for an SMS text message when logging in on a new device. While this doesn’t protect against SIM swapping attacks, you can potentially decrease the likelihood of this happening if you register with a Google Voice number.

Delete your location

Sharing your location could allow someone to find your physical location. While that might not seem like a big deal at first, people have reportedly been robbed based on the timing and location of their tweets.

Remove or Limit Applications

Each time you connect Twitter with an application, you are increasing your attack surface. While most Twitter apps are innocuous, a flaw in a third-party application means someone may be able to gain access to your Twitter data using the application. Be especially cautious around applications that have both read and write permissions, as this means the worst case scenario is that someone could send a tweet as you.

Opt out of Twitter’s personalization

To remove the sharing of personalized information to other parties such as 3rd party advertisters, go to “Privacy and Safety” and turn off everything under “Personalization and Data”.
