security - How do I use my Google account when I have a FIDO U2F Key attached?



I have recently attached a FIDO U2F Key to my Google Account to make it more secure. How can I now actually log into my Google Account on Android again?


Whenever I try to log in, it says wrong password, even though I know it is the right password. Does anyone know what is required to get it working again?



Answer



To log into GMail after attaching any sort of 2 Factor Auth, one has to create an Application specific password for use with your Google Account. For that, you have to to the Authorization Page in your Google Account, enter a custom name and google will create a secure password that one can use with any device. This password is only visible once after creation, so if you need to log in again, just create a new one, which is safer than writing it down.
