Am I the only person in the world who doesn't have a cell phone? It annoys me that the two-factor auth setups at sites (like Google) assume I have one and don't even have an option for "I don't have a cell phone, please stop nagging me about this."

You can use a YubiKey for Google 2-factor along with a helper app like Yubikco's "sidekick" for Windows [1] or my company's OneTime on Mac [2]. A YubiKey costs about $25 but is very portable, fast and convenient option.

The reason I'm not using 2FA right now is twofold. First, because Google doesn't have half of their services using it for some undefined reason (for at least a year plus!). Also, the whole "app specific password" thing is a huge pain in the ass. (And appears to randomly stop working on say, IMAP mail).

Second, because the mobile authenticator is not feasible for me right now. I do a lot of android development work (well, mostly screwing around, but we'll call it work) on the side, with the result that I'm wiping my phone for romflashes at least once a week. Makes everything going through a mobile app a little useless.

I really wish Google would support a hardware token of some kind.

Something Google could to do drastically improve the security of their two-factor authentication system is to add the ability to give more granular permissions with the application-specific passwords. I have an application that only needs to send E-Mail through my GMail account (git-send-email), another that only needs to write to one specific GMail label (Android SMS Backup), and Google Chrome surely doesn't need ac…

Maybe you should use throwaway accounts for these purposes? That is, have a gmail account for github to send your patches through, and have that forward to your main email account?

In the SMS-backup case...how important is it that you access your SMSes in your Gmail account? My first thought is: it's bad enough that someone breaks into my email, nevermind all my SMSes. But I guess if you have a workflow that requires easy access to SMSes with your email, you can still have a separate email account that does nothing but forward it onto your main account.

So your main account, theoretically, has strong security with the two-factor authentication without having to make backdoors for external apps. People can always break into your throwaway accounts, but they'll have no particular inroad into your main account.

And presumably, you'd have a decent window of time to detect an intrusion and administer the throwaway accounts with your main GMail account

Yes, can someone explain why Google Chrome doesn't support 2FA on the desktop or iOS? It's bizarre.

(Well, I suppose it's tragically normal. I'm sure there is a corporate directive that says every Google service must support 2FA, but Chrome has an exception so they don't need to do it yet.)

I hear a lot of people advising to turn on two factor auth on Google because of this incident, but I haven't heard anyone say that we should be deleting our card details from Amazon. Well, I have, and you should too. Lots of places use the last 4 digits of your card as "authentication", and Amazon happily displays those details in your account.

Note that they had to break into the account in order to view those last 4 digits. You seem to be implying that they show them to anyone.

Either way, using the last 4 digits as 'security' is just stupid. You can get those from a receipt.

I was worried this would be a major pain when I enabled it, but I have to say, it has been much more painless than I thought it would be. Most of the time, I don't even think about it. Most of my consumption of google mail is through clients on my laptops, iPhone, or iPad. So in that sense, it's not much different from a regular password. The difference is that someone else has a much harder time cracking my account.…

Why wouldn't two-factor authentication protected Mat from at least his GMail account being hacked? Even if password-resets were being sent to the .Me account, wouldn't the hackers still need to generate the authentication token?

I just turned two-factor authentication on and it forced me to set "program specific" passwords for like 10 different apps and seriously messed up my phone. I had to deactivate it. What's with the hassle?

For the second factor to mean anything, all the apps that don't support it need a password that has less rights. Hopefully they figure out a nice way to make the rights more granular (so that a chat app can't mess with email or whatever).

Yeah, unfortunately it seems like the only rights it is missing is "update account information". Which is not much good when you are trying to protect your data.

Two-factor auth gets old really fast when you have to use public computers in a setting like a college library. I had turned it on for a while, but turned it off when I had 5 minutes to print out a paper that I had emailed myself (yes, I still do that) and was fiddling with my phone to get the damn PIN. Never again.

To me, the use case you describe would make me very happy to be using two factor auth - logging into a very important personal account using untrusted, public computers I don't control. I'd be glad for the extra hassle with that.

According to Matt (and, apparently, his hacker) you're wrong; two-factor would have saved him in this particular instance: "If I had some other account aside from an Apple e-mail address, or had used two-factor authentication for Gmail, everything would have stopped here." (http://www.wired.com/gadgetlab/2012/08/apple-amazon-mat-hona...)

Naturally, it's not a panacea, but I think a lot of people allow perfect to be the enemy of quite good when it comes to two-factor auth.
