[GCP] IAM Finally Introduced to Cloud SQL Studio.

Previously, when using the Studio feature in Cloud SQL on GCP, we had to log in using a password, even if it wasn't actually necessary. The problem was that since we didn't usually use the password, we always forgot it, and this forgetfulness posed a significant security risk.

However, today, Cloud IAM login functionality has finally been added.

Select the Database and click the [Authentication] button at the bottom to log in and start using it immediately.

In fact, logging in with individual user accounts is significantly safer than using a password. Furthermore, with the recently added feature allowing IAM accounts to be registered as "Groups", usage has become even safer and more convenient.

When accessing the system, using a Service Account for system access and a group or user for user access via IAM provides significantly better security and convenience.

Of course, even so, in the case of pgSQL, there are occasional instances where it is necessary to log in with the postgres account. However, even considering this, it's still much better than having no such functionality.

Despite the recent updates to various features, most people only focus on updates to generative AI. However, these small updates also bring significant convenience, so it's worth paying attention to them.
