    Can anybody let me know the pros and cons of enabling 2-factor verification on my MBPr so my watch will unlock it?

    I also use an iPhone 6sPlus and iPad Air2 and would like to have the 2FV only impact the MBPr, but I would imagine I have to embrace it across all Apple devices or when logging into

    Any insight would be appreciated,

    Hey Doth,
    I didn't find 2FV to be a problem at all. We have similar equipment - iPhone 7Plus, iPad Air 2, Apple watch and MBPr. I’ve had 2FV on for a while and now I’m enjoying the watch unlocking my MBP. Occasionally, it burps and requires my password but over the last couple of days I’ve had to enter my password maybe 3 times (out of maybe 20 or so). This was probably due to operator error on my part.

    My iPhone and iPad are always logged into iCloud so there is no additional verification required.

    On the Mac when you sign out of iCloud there is a check box allowing it to remember the browser so you do not have to go through the 2FV process again.

    All in all, I have not noticed any problems with 2FV. I’ve been using 2FV for a while now - probably a month or so. Allowing the watch to sign into the Mac is magic ,.. lol.. enjoy!

    Hey Bill,

    I am so appreciative. I was worried that making it easier on the Mac would require me to always enter my password and then obtain a code every time I turned on one of my other devices.

    I will have to give it a try. Do you think if I don't like it, I can return to how it is without the 2FV?
