The command "gcloud auth login" is used to authorize access to the Google Cloud Platform using the command-line interface (CLI) tool known as "gcloud".
When you run this command, it initiates the login process, prompting you to authenticate with your Google account. It opens a web browser window where you can sign in with your credentials. After successful authentication, a token is generated, which is then stored locally on your machine.
This token allows the gcloud CLI tool to access and manage your Google Cloud Platform resources on your behalf, such as creating and managing virtual machines, deploying applications, or accessing storage and database services.
Once you have logged in and the authentication token is stored, you can use other gcloud commands to interact with various Google Cloud Platform services without the need to authenticate again, unless the token expires or is revoked.
