I used the account signed into Windows, which does not have access. It should have timed out, rather than just sitting there for ten minutes.

@jiasli please take a look.

I have fixed az login hang issue in #10955. If the account doesn't have access, instead of hanging, CLI will show

No subscriptions were found for 'xxx'. If this is expected, use '--allow-no-subscriptions' to have tenant level access

If you still see this issue, please run az login --debug and share the result to my email <my_github_id>@microsoft.com
