Twitter Now Lets You Use A Security Key As Your Only 2FA Method

After announcing support for multiple security keys in March, Twitter now lets you use one as your only two-factor authentication method.

Back in In March, Twitter announced support for multiple security keys on its app, and said it would soon let you link more than one security key to use for two-factor authentication (2FA) – as well as use a security key as your own 2FA method.

Well, the day has come, and you can now use just a physical security key to secure your Twitter account. This is great news, as physical keys are currently the most secure method of protecting your online accounts.

While using an authenticator app is definitely more secure than using a code sent via SMS or Bluetooth, a physical key is probably the most secure option.

The feature is now available on both mobile and web versions of the app.

Now security keys can be your one and only two-factor authentication method on mobile and web.
