I currently have Duo and a YubiKey associated with my LastPass account as multifactor authentication (MFA) options. When logging into LastPass on the browser, I am prompted to use the YubiKey but I can choose to use Duo if I select "Additional Multifactor Options". When logging into LastPass on mobile, Duo immediately sends a push notification but I can select to use the YubiKey by tapping on "Verify with Code", then "Use Alternate Multifactor", then selecting "YubiKey" (this is an IOS device).
REQUEST: It would be helpful to choose the default MFA option so it can be consistent between the desktop and mobile versions. Additionally it would be helpful to determine which devices are allowed which type of MFA (i.e. mobile is only allowed to use a Yubikey while the desktop browser can use either Duo or YubiKey).
