configuring an asset with two authentication methods

Can i configure an asset with two authentication methods? for example a user must access the LinuxAsset asset with user and pw injection and another user must access the same asset with ssh key authentication. Is it possible? Are there no conflict problems?Do I have to upload the asset twice in SPP, once with user and pw and another time with SSH key in the connection tab of tha asset? (the need is to give access to two different user groups using two different authentications, if it is possible)
