az aks get-credentials with custom ssh key?

So we have our own ssh key pair (mykey.pub / mykey).
User A creates a cluster using:

az aks create --resource-group XXX --name zzz --ssh-key-value c:\mykey.pub

Now user A can access the cluster using:

az aks get-credentials

Now what if user B wants to access the cluster? There is no –ssh-key-file parameter like acs – where do I need to copy the keys for az aks get-credentials to work?

Thx –
