In March, Twitter had said it would soon let people use a security key as their only two-factor authentication method.
It protects against interception of data by ‘hackers/attackers’ and twisted data can only be decrypted with the encryption key
Starting from Friday, the users can set up two-factor authentication and log into Facebook on iOS and Android mobile devices globally, including India, using a security key.
Currently, Twitter users can use a security key to sign in and also need an authenticator app or SMS code as another 2FA (two-factor authentication) method.
