I am using LP and Authy to a small degree.  Yubikey would prompt a more comprehensive, single-entry solution.

I am already using those OTP for 2FA for various accounts.  But I really want to use a Yubikey for my gmail.  :)

Currently I use Microsoft authenticator but still it is software based only as this also an app, it will be great to have a physical key which gives more protection in the world of internet where security is always a question, not sure how you will be affected. It will be a great pleasure to use a Yubikey with NFC which will give me a extra layer of security. did some research now on this and could see this is one of the best two factor authentication device to use. Good to be part of it.

I use Microsoft Authenticator,  SecurID (Replaced RSA Token), and Authy.

I use my phone for most MFA (Authy, SecurID, Authenticator) on a computer. However, having a USB-C Yubikey to secure logins on my phone would be awesome. Not sure how well supported that is, so happy to experiment and report back ;-)

Google authenticator and txt. 

No 2FA other than banking, this would be the kick up the bum i need to get it sorted.

Thanks!

What a great giveaway. I use 2FA / MFA in various forms, but want something that can be more standardised. Would be awesome to get hold of a yubikey and try this out.
