1. A method for providing a restricted-access messaging service in a server, wherein first-authority-level users are authorized to access the messaging service and are able to request access to the messaging service for second-authority-level users who are not otherwise authorized to access the messaging service, the method comprising:
receiving, from a first terminal, (i) an invitation from a first-authority-level user inviting a second-authority-level user to join a workspace of the messaging service, (ii) a first identity identifying the first-authority-level user, (iii) a second identity identifying the second-authority-level user, and (iv) information identifying the workspace to which the second-authority-level user is invited by the first-authority-level user;
determining, based on the first identity, that authorization is required for the invitation to grant the second-authority-level user access to the workspace, and based thereon transmitting an authorization request to an approver;
receiving, from a second terminal, an authorization confirmation granted by the approver based on the authorization request;
based on the authorization confirmation, the second identity, and the information identifying the workspace, performing a workspace member registration procedure that registers the second identity as a member of the workspace, and
deleting an account of the second-authority-level user from the restricted-access messaging service responsive to the second-authority-level user being exited form the workspace and being determined not to be registered as a member of another workspace, and transmitting an account deletion notification using the second identity.
