Twitter has had two-factor security based on physical keys, like the Yubikey or Google's Titan keys, for a long time. You've been able to log in with said keys on your phone (assuming your key works with your phone) for a few months. But what if you have to manage your company's PR Twitter account while on the go? Or more typically, what if you have a USB-A key for your desktop and an NFC key for mobile usage?

In either case, the Twitter app for Android now supports logging into one or more accounts via multiple physical security keys, be they USB, Bluetooth, or NFC. Twitter announced the change via a tweet, naturally, and it appears to be live in the latest version of the app.

At the moment you still need to log in with your Twitter password, but Twitter said that soon you'll have the ability to log in with only a security key enabled. Which is, you know, just one-factor security, but it's probably more secure than the same password you've used on two dozen other services.

Login via security key alone now supported

As promised, the Twitter Android app can now log into your account with just a USB, Bluetooth, or NFC-based security key as your sole 2FA method. It works with multiple keys, though they'll need to be associated with your account before you try logging in on mobile. You might want to make sure everything's working on a full desktop browser before trying it on your phone alone.
