Count me in as another advocate for two-step verification for the Fido app. Someone hacked into my account and ordered themselves an iPhone and changed my phone plan. While I have no doubt that Fido will reverse the fraudster's actions, it would've been nice to have measures in place to lower the possiblity of this event in the first place.
I agree, I'd love to be able to secure my account with 2FA. I use Google Authenticator for many of my online accounts. With SIM swapping attacks on the rise I'm looking for ways to be proactive in locking down my mobile accounts, especially now that the CRA uses mandatory SMS 2FA (big yikes). If security is one of Fido's top priorities I believe this feature would have been added a long time ago. This is a feature I'd strongly consider switching carriers for. Please pass along this feedback, FidoNick! Cheers
