Operational team needs administrative SSH access to many Compute Engine VMs; each employee has a Google account. To deploy credentials efficiently and ensure access is attributable, what should you do?

The correct approach leverages OS Login, which integrates SSH access with Google identities. By having each team member generate their own SSH key pair and adding the public key to their Google account, their SSH access is directly tied to their individual identity. Granting the compute.osAdminLogin role to a Google Group simplifies management; all members of that group automatically gain administrative SSH access to VMs with OS Login enabled. This method ensures individual accountability and centralized access control. Distributing a single private key (options 1 and 4) is insecure and makes accountability impossible. Manually collecting and deploying individual public keys via a configuration management tool (option 2) is less efficient and scalable than OS Login, and it doesn't inherently link SSH access to Google identities for auditing.
