Twitter has long had dual security features based on physical keys like Ubiquiti or Google’s Titan Key. You can login with this key on your phone (assuming the key works on your phone). for several months. But what if you need to manage your company’s PR Twitter account on the go? Or, more generally, what if you have a USB-A key for desktop and an NFC key for mobile?
In both cases, the Twitter app for Android now supports logging into one or more accounts via multiple physical security keys such as USB, Bluetooth or NFC. Twitter has of course announced this change via a tweet and it will be live in the latest version of the app.
Protect your account (and its changes) with multiple security keys. You can now register and login using multiple physical keys on mobile and web.
Coming soon: You have the option to add and use a security key only as an authentication method without using any other method.

Login is now only supported with a security key.
As promised, the Twitter Android app is here. Log in to your account As the only 2FA method, all you need is a USB, Bluetooth or NFC-based security key. It works with multiple keys, but must be associated with an account before attempting to log in on mobile. It’s a good idea to make sure everything works in the full desktop browser before trying it on your phone only.
Security keys can now be the only two-factor authentication method on mobile and the web.
