We are currently using both NK-SHIPS and NK-PASS, and have multiple login IDs for each system. Is it possible to register the same email address for each of these login IDs?

If you are using multiple services such as NK-SHIPS and NK-PASS and have multiple login IDs, pre-registration is required for each login ID individually.
It is possible to register the same email address for multiple login IDs.
However, within a single login ID, the same email address cannot be registered for both the "Administrator" and "Normal user" accounts.

[Example]
【OK】Login ID: AA1234 / Login ID: BB1234
Both can be registered with taro_kaiji@classnk.or.jp

【NG】Login ID: CC1234
Cannot register hanako_kaiji@classnk.or.jp for both the administrator and general user accounts under the same login ID.
