gcloud source repos clone - fatal: remote error: Access denied to <my former email account>

[thstart]

My development machine is macOS.

I did initial test for Google Cloud and AppEngine. Did source control upload/download just fine.

Now registered with new email account.

Trying to do the following:

gcloud source repos create my-cool-repo

gcloud source repos clone my-cool-repo

got the error:

fatal: remote error: Access denied to <my former email account>

I did gcloud init && git config credential.'https://source.developers.google.com'.helper gcloud.sh

But seems my former email account is somewhere in a cache.

I checked in macOS keychain for git and it is not there.

How to make it work?
