The mc admin user svcacct add command adds a new access key to an existing MinIO or AD/LDAP user.

The following command creates a new access key associated to an existing MinIO user:

mc admin user svcacct add                       \
   --access-key "myuserserviceaccount"          \
   --secret-key "myuserserviceaccountpassword"  \

   myminio myuser

The command returns the access key and secret key for the new account.

Behavior

S3 Compatibility

The mc commandline tool is built for compatibility with the AWS S3 API and is tested with MinIO and AWS S3 for expected functionality and behavior.

MinIO provides no guarantees for other S3-compatible services, as their S3 API implementation is unknown and therefore unsupported. While mc commands may work as documented, any such usage is at your own risk.
