Root Access Settings

This page covers settings that control root (superuser) access for the MinIO process. The root user has complete access and permissions to perform operations on the MinIO deployment.

Root User and Root Password are required even if you use the MinIO Key Encryption Service or other key management utility.

You can establish or modify settings by defining:

• an environment variable on the host system prior to starting or restarting the MinIO Server. Refer to your operating system’s documentation for how to define an environment variable.
• a configuration setting using mc admin config set.

If you define both an environment variable and the similar configuration setting, MinIO uses the environment variable value.

Some settings have only an environment variable or a configuration setting, but not both.

Specify on to enable and off to disable the root user account. Disabling the root service account also disables all service accounts associated with root, excluding those used by site replication. Defaults to on.

Ensure you have at least one other admin user, such as one with the consoleAdmin policy, before disabling the root account. If you do not have another admin user, disabling the root account locks administrative access to the deployment.

You can use this variable to temporarily override the configuration setting and re-enable root access to the deployment.

To reset after an unintentional lock, set MINIO_API_ROOT_ACCESS on to override this setting and temporarily re-enable the root account. You can then change this setting to on or make the necessary user/policy changes to ensure normal administrative access through other non-root accounts.
