gcloud alpha auth list

NAME
gcloud alpha auth list - lists credentialed accounts
SYNOPSIS
gcloud alpha auth list [--filter-account=FILTER_ACCOUNT] [--filter=EXPRESSION] [--limit=LIMIT] [--page-size=PAGE_SIZE] [--sort-by=[FIELD,…]] [GCLOUD_WIDE_FLAG]
DESCRIPTION
(ALPHA) Lists accounts whose credentials have been obtained using gcloud init, gcloud auth login and gcloud auth activate-service-account, and shows which account is active. The active account is used by gcloud and other Google Cloud CLI tools to access Google Cloud Platform. While there is no limit on the number of accounts with stored credentials, there is only one active account.
EXAMPLES
To set an existing account to be the current active account, run:
gcloud config set core/account your-email-account@gmail.com

If you don't have an existing account, create one using:

gcloud init

To list the active account name:

gcloud auth list --filter=status:ACTIVE --format="value(account)"

To list the inactive account names with prefix test:

gcloud auth list --filter="-status:ACTIVE account:test*" --format="value(account)"
FLAGS
--filter-account=FILTER_ACCOUNT
List only credentials for one account. Use --filter="account~PATTERN" to select accounts that match PATTERN.
LIST COMMAND FLAGS
--filter=EXPRESSION
Apply a Boolean filter EXPRESSION to each resource item to be listed. If the expression evaluates True, then that item is listed. For more details and examples of filter expressions, run $ gcloud topic filters. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.
--limit=LIMIT
Maximum number of resources to list. The default is unlimited. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.
--page-size=PAGE_SIZE
Some services group resource list output into pages. This flag specifies the maximum number of resources per page. The default is determined by the service if it supports paging, otherwise it is unlimited (no paging). Paging may be applied before or after --filter and --limit depending on the service.
--sort-by=[FIELD,…]
Comma-separated list of resource field key names to sort by. The default order is ascending. Prefix a field with ``~´´ for descending order on that field. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.
GCLOUD WIDE FLAGS
These flags are available to all commands: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.

Run $ gcloud help for details.

NOTES
This command is currently in alpha and might change without notice. If this command fails with API permission errors despite specifying the correct project, you might be trying to access an API with an invitation-only early access allowlist. These variants are also available:
gcloud auth list
gcloud beta auth list
