It looks like this is a known issue, and Google is on top of it. From the product forums: We've gotten reports about some users being signed out of their accounts unexpectedly.

Google found that security questions were not really secure at all as most of the answers can be found with a simple Google search. For example Sarah Palin had her Yahoo! account hacked because someone simply Googled her birthday, ZIP code and where she met her spouse. Google has completely removed support for security questions and one only had the ...

The OAuth tokens for Google are at https://accounts.google.com/b/0/IssuedAuthSubTokens (it's different from Linked Accounts). When I tried it, Facebook created a popup with a OAuth prompt the first time and only briefly opened a blank popup on subsequent attempts. De-authorizing Facebook makes the prompts appear again.

No! Don't give your portrait to Gravatar. Regardless of whether you trust Gravatar Corp, site owners can carelessly betray the identity of users posting under pseudonyms.

You can generate one time codes that can be used as part of two-step verification that doesn't require your phone.

Unfounded. You need to be authenticated to actually view any emails. Just to show you how sure I am, here is a link to one of my emails. Unless you are authenticated as the user who "owns" that email, it will just redirect you to the inbox (tested with another account).

I'm the Gmail Community Manager. I spoke with our team about what you described. What you are seeing is a bug in our system related to the use of IPv6. Very specific types of logins to do with mobile phone syncing that come in over IPv6 are not currently treated correctly. We're in the process of fixing this issue and I apologize for the inconvenience.

Clear the browser's cookies (and perhaps cache/history). 'Trust this computer' option doesn’t work For computers you trust, Google recommends you select the "Trust this computer" option when you are asked for a verification code.

You can create redundant code before your device is lost or a reason. Deactivate MFA, then configure and enable a virtual MFA device for use.

Yes, you can use the same phone number or address in your contact information. However, you can't verify multiple accounts with the same number.

Authenticator works even when you don't have any sort of network available for your smartphone. I don't know about your mobile provider, but I don't trust mine to deliver SMS messages in anything that resembles a timely manner. Beyond that, it is more secure, as you've noted.

You really can't stop them from trying but you can make your account more secure. For GMail / Google account I would setup the 2 step authentication. The 2 step process links your smartphone to your account so when you log in and get through, google will also send you a pin to your smartphone from which you will then verify. Much more secure.

Google is probably using information that it has not specifically requested of you during the password reset process in order to verify your ownership of the account. Specifically, tokens stored on your computer, and your IP address. I had a similar experience to yours, which initially alarmed me, and tested the above theory by using the Tor browser to ...
