2-factor authentication and time

Flinders Street StationI use Google Authenticator for 2-factor authentication for some of the services I access. I had trouble accessing some of my sites due to getting an invalid token, and I was wondering what was going on.

Turns out, the time on my phone was off. You need to let the network set the time, and you will suddenly be generating sensible codes again. This is documented for Android (you can do this within the app), but on iOS it is a system-wide setting.

When Google locks you out

I came home after a long day of activities to find myself locked out of my Google account. I was told that there was suspicious activity and it had decided to lock me out. 

The verification code to set everything going is via a text message to your phone. After that you enter a completely new password. 

Now comes the fun. You have to regenerate codes for all your 2-step authentication authenticated applications. This is a huge pain for me – iPhone, Galaxy S3, Nexus 7, BlackBerry, Mail, Adium, etc. The list is really long. 

Overall this seems counterintuitive. I checked my account history. I did get connected via one odd IP today, but beyond that, nothing. It was me, my mail client connected from that IP.

Saw a bounce. Seems that I forwarded a message from google groups, it got rejected, and automatically it triggered that I might be a spammer. Seems like a bug more than anything.

Overall, I spent about 45 minutes just sorting out this problem. There has got to be a better way considering how important the Google account is to us these days. I didn’t notice a phone number either so if I needed to call someone, I’d probably be quite out of luck.
