+#### Using a certificate key pair instead of the shared secret
+
+- Generate a key pair, e.g. with:
+```bash
+openssl genrsa -out private.key 2048
+openssl req -new -x509 -key private.key -out publickey.cer -days 365
+```
+- Upload the `publickey.cer` to your app in the Azure portal
+- Note the displayed thumbprint for the certificate (it looks like `B4A94A83092455AC4D3AC827F02B61646EAAC43D`)
+- Put that thumbprint into the `clientCertificateThumbprint` constructor option
+- Put the contents of `private.key` into the `clientCertificatePrivateKey` constructor option
+- You can omit the `clientSecret` constructor option
