B2B AS2 Adapter - URL access without Credentials

Hi Experts,

We are using Seeburger AS2 adapter for AS2 communication in SAP PI 7.4 SP 06.

Earlier we  have shared the connectivity details with the partner  like seeburger url and other details, to access the same from partner side the credentials are not mandatory.

Now . we are planning to migrate from Seeburger to B2B AS2 adapter provided by SAP for the same we need to share the B2B URL with the partner and it requires username and password to access the same.

Is there any way that we can surpass this ?

Thank you in advance.

Regards,

Srinivas
