Logs in to Azure Active Directory to access Azure Storage resources.
Log in to Azure Active Directory to access Azure Storage resources.
To be authorized to your Azure Storage account, you must assign the Storage Blob Data Contributor role to your user account in the context of either the Storage account, parent resource group, or parent subscription.
This command will cache encrypted login information for current user using the OS built-in mechanisms.
If you set an environment variable by using the command line, that variable will be readable in your command line history. Consider clearing variables that contain credentials from your command line history. To keep variables from appearing in your history, you can use a script to prompt the user for their credentials, and to set the environment variable.

Log in by using the system-assigned identity of a Virtual Machine (VM):
azcopy login --identity
Log in by using the user-assigned identity of a VM and a Client ID of the service identity:
azcopy login --identity --identity-client-id "[ServiceIdentityClientID]"
Log in by using the user-assigned identity of a VM and an Object ID of the service identity:
azcopy login --identity --identity-object-id "[ServiceIdentityObjectID]"
Log in by using the user-assigned identity of a VM and a Resource ID of the service identity:

Log in as a service principal by using a client secret: Set the environment variable AZCOPY_SPA_CLIENT_SECRET to the client secret for secret based service principal auth.
azcopy login --service-principal --application-id <your service principal's application ID>
Log in as a service principal by using a certificate and it's password:
Set the environment variable AZCOPY_SPA_CERT_PASSWORD to the certificate's password for cert-based service principal auth:
azcopy login --service-principal --certificate-path /path/to/my/cert --application-id <your service principal's application ID>
/path/to/my/cert as a path to a PEM or PKCS12 file. AzCopy does not reach into the system cert store to obtain your certificate.
--certificate-path is mandatory when doing cert-based service principal auth.
--aad-endpoint string The Azure Active Directory endpoint to use. The default (https://login.microsoftonline.com) is correct for the global Azure cloud. Set this parameter when authenticating in a national cloud. Not needed for Managed Service Identity.

--certificate-path string Path to certificate for SPN authentication. Required for certificate-based service principal auth.

Options inherited from parent commands
|--cap-mbps float||Caps the transfer rate, in megabits per second. Moment-by-moment throughput might vary slightly from the cap. If this option is set to zero, or it is omitted, the throughput isn't capped.|
|--output-type string||Format of the command's output. The choices include: text, json. The default value is "text".|
|--trusted-microsoft-suffixes string||Specifies additional domain suffixes where Azure Active Directory login tokens may be sent. The default is '.core.windows.net;.core.chinacloudapi.cn;.core.cloudapi.de;.core.usgovcloudapi.net'. Any listed here are added to the default. For security, you should only put Microsoft Azure domains here. Separate multiple entries with semi-colons.|
