One-liner:

export OS_NS="openfaas"
# Get password
export OF_PASS=$(echo $(kubectl -n $OS_NS get secret basic-auth -o jsonpath="{.data.basic-auth-password}" | base64 --decode))
echo $OF_PASS
# Get URI
echo "export OPENFAAS_URL=http://"$(kubectl -n $OS_NS describe pods $(kubectl -n $OS_NS get pods | grep "gateway-" | awk '{print $1}') | grep "^Node:" | awk -F "/" '{print $2}')":31112"
echo $OF_PASS | faas-cli login --password-stdin
