I accidentally wiped the data on my Android device losing all my Google 2-factor authentication tokens.
Using the Google Authenticator plugin for WordPress by Henrik Schack meant I was now unable to login to my blog. In order to login to my blog, I would need to either erase the plugin removing the 2-factor authentication (rm wp-content/plugins/google-authenticator/), or obtain the secret key and add the secret key back to the Google Authenticator application on my Android device. Rather than erase a plugin I wanted to use, I started searching for the key. Unfortunately, I wasn’t able to easily find this information.
I manually started searching through the WordPress database and found the secret key under the usermeta table in the field called googleauthenticator_secret. Providing this key to the Google Authenticator application allowed the application to start generating the login tokens again and allowed me to log back into my blog!
Hope this helps somebody else in the same situation!
