I remember once consulting one of my client who used GCP and to get SSH to one of the instances where pain in ass, I spent couple of hours on that.

If I recall correctly they do have concept of users and then user gets SSH key and you can't just put SSH key on instance out of the box as on any other VPS...

They make it pretty easy to SSH in through both the console and with the gcloud command. If you set it up correctly, Linux user accounts are tied to GCP IAM accounts and are automatically provisioned. It's actually super slick! Maybe your client didn't want to do that.
