If you want to lock your account on your Twitter account, you can enable SMS authentication two (2FA) or create a one-time login code.
But today, you can also use third-party authentication applications like Google Authenticator and Authy.
The company has reportedly added support for third-party apps, but hasn't announced it yet.
Let's see how you can set up the new security feature:
Install one application two-factor authentication like Google Authenticator or Authy, and create your personal account on your phone (just follow the instructions the apps give).
Connect with Twitter through it browser σας και πηγαίνετε στις Ρυθμίσεις μέσω του "Λογαριασμός.".
Ανοίξτε την καρτέλα "Ασφάλεια", και επιλέξτε το πλαίσιο που λέει «Επαλήθευση σύνδεσης» και πληκτρολογήστε τον κωδικό επαλήθευσης που θα λάβετε μέσω SMS.
Στη συνέχεια, κάντε κλικ στο κουμπί με την ένδειξη "Ρύθμιση εφαρμογής κωδικών." 
You will see the instructions along with a bar code. Start the 2FA application on your phone and use it to scan the bar code.
Ο account of Twitter will be created in the 2FA application you selected and see along with a six-digit code. The next time you try to log in to Twitter, you'll be asked to enter this password, which changes every few seconds.
Apps work even if your phone is not connected to the Internet.
That's it. You no longer have to worry about hackers finding your Twitter password.
