If you’re operating Google workspace without a well oiled Enterprise behind the scenes, a single admin account is a single point of failure.

I had this happen a couple years ago when I was migrating to a different domain. The only difference was all of the authentication that I supplied Google said was an adequate and I got into some sort of a login loop where Authenticator, SMS, DNS record nor pass key would provide enough authentication for me to get in.

I got the automated got bought to finally send me the mythical form, after completing that I was told that they were unable to authenticate me further. I ended up emailing their support multiple times and threatening lawsuits multiple times when I got a magic call from a human at Google. They also sent me the link that put me into a login loop however after chatting with them for nearly an hour I got a different magic login link form which appeared to work.
