Advanced Twitter account security guide

Surely you used your phone number to authenticate two Twitter accounts. However, if you want to really secure your account, you should consider creating an application-specific password.

This job is extremely simple, you just need a computer, a mobile phone and a third-party authentication application.

Some typical applications:

• Duo Mobile
• Google Authenticator
• Authy

The reason why you should do this is because it's safer. Validating Twitter 2 elements by SMS can be attacked when someone hijackes your mobile account. (For example, an attacker may require a new SIM for your account from a service agent). Meanwhile authentication by application is more difficult to attack even when you change phone numbers or lose access to the device.

1. From your computer, click the profile icon.

2. Click Settings and privacy .

3. Click the Review your login verification methods button in Security .

4. Enter the password then click Confirm .

5. Click Set up next to Mobile Security app .
