I enable the two step authenication, but when logging in it asked to enter the code from authenticator app. I tried to setup google authenicator on my phone app, but it asked for a key. Tried my recovery key,but that did not work, so which key is it referring to? I also tried to search apps through Atassian Marketplace to connect apps through Atlassian account, but google authenticator app does not show up to download. How does this work then? Thanks.
