Here’s my Bash script to login to both AWS and GCP. It has a little bit of intelligence. It checks if you are already logged in, and skips if you are. If not logged in, it will open up the cloud web console which is protected by Okta. The script has been redacted and replace with generic usernames and web pages for security reasons.
