How to Create a Service Account in Google Cloud

Introduction

A service account in Google Cloud is a special account used by applications instead of humans. It helps authenticate and authorize access to Google Cloud services securely. Service accounts are essential for automating tasks and protecting your data

Why Use a Service Account?

Service accounts provide several benefits:

1. Secure API Access: Applications can safely connect to Google Cloud without user credentials.

2. Controlled Permissions: You can set roles to limit what the service account can do.

3. Automated Tasks: Ideal for scripts, data processing, and background jobs.

4. Easy Authentication: JSON key files allow seamless login for applications.

• Rotate Keys Regularly: Generate new keys and delete old ones.
  
  
• Use Workload Identity Federation: For better security, use Workload Identity instead of JSON keys.
