Configuring Your Registration
Password
Applicable to: remote role assignment, remote delta links, WSRP application sharing (for NetWeaver consumers only)
For increased security, you can set a registration password, which a NetWeaver consumer need to enter upon registration with your producer portal (see Registering Your Consumer Portal).
The procedure described here is only applicable for NetWeaver consumers. For non-SAP consumers, you need to set up consumer-specific users on your producer portal (see Creating Users for Non-SAP Consumers).

This is a global setting for all NetWeaver consumers; you cannot set a different registration password for each consumer.

1. In the producer portal, navigate to System Administration ® System Configuration ® Service Configuration.
2. In the Portal Catalog, navigate to the com.sap.portal.ivs.wsrpservice application.
3. Open the AutoGenProducer1_0service.
4. Enter a password in the REGISTRATION_PASSWORD property.
The default password is password. If you enter a blank password, the consumer does not request one upon registration.
