Twitter will soon let you use a security key as your only 2FA method
Twitter is planning a future update that will allow accounts enabled with two-factor authentication to use security keys as the only authentication method, the company said on Monday.
At present, you can use a security key to sign in to your Twitter account, but you need to have another 2FA method — like an authenticator app or SMS codes — enabled as backup.
While authentication apps like Google Authenticator or Authy are more secure than using SMS codes for 2FA, security keys — physical keys that connect to your computer using USB or Bluetooth — are the most secure way to protect an account online. Users don’t have to type in a code that could be intercepted by a malicious third party.
