 To store the access token in a variable to use in subsequent commands to authenticate, run the following command:
 
 ```bash
-token=$(curl 'http://169.254.169.254/metadata/identity/oauth2/token?api-version=2018-02-01&resource=https%3A%2F%2Fvault.azure.net' -H Metadata:true | jq -r '.access_token')

 ```
 
 Now use the access token to authenticate to key vault and read a secret. Be sure to substitute the name of your key vault in the URL (*https:\//mykeyvault.vault.azure.net/...*):
 
 ```bash
-curl https://mykeyvault.vault.azure.net/secrets/SampleSecret/?api-version=2016-10-01 -H "Authorization: Bearer $token"
+curl https://mykeyvault.vault.azure.net/secrets/SampleSecret/?api-version=2016-10-01 -H "Authorization: Bearer $TOKEN"
 ```
 
 The response looks similar to the following, showing the secret. In your code, you would parse this output to obtain the secret. Then, use the secret in a subsequent operation to access another Azure resource.
