I don't use 2FA at the moment but am aware that I should. If I don't win I might have to look at purchasing a key

Currently using Microsoft Authenticator for work access.

Using authy and 2FA authentication for apps.

Using 1Password converted as much as possible to 2FA, and using MS Authenticator for work..

I still have. Few things using plain SMS that need retiring

Wow  this is sweet. I have been using 2FA for quite  some time for most of my services. I use mix of Authy, Google Auth, Microsoft Auth both for work and  personal.  Having a physical  Key would be great for  not  having to swap  between all  these apps all the time.!

2FA is an absolute must these days. I try and use TOTP as much as I can these days. I've never really looked into hardware tokens, but a Yubikey would really up my security game.

Never used a hardware based key and would like to use one! Currently use Bitwarden + Aegis authenticator on android. A hardware based key would certainly be a neat addition to the personal threat model!

I'm using Google Authenticator primarily for email and cloud storage accounts along with (mostly) unique passwords managed by LastPass. It's a slow and gradual process to get the family to see the value in adopting the same measures for theirs...

I use Authenticator Pro on Android for 2FA and I have used Yubikey previously in conjunction with LastPass. They are great devices. 

I use Authy & Google for all my 2FA. The Yubikey would make things a lot simpler.

Good Luck everyone.

The usual MFA, Google and Duo for corp related authentication.

Personal MS account, gone with password less via the MS Auth App.

I love Windows Hello and its revolutionary for Hello for Business

Keen as! I've got an old YubiKey for a few services, then Authy for everything else.

I use 2FA on Google and Microsoft.  A USB that secured these and other sites would be great!
