Answer 1

Since you are accessing an Azure service from a non-Azure service, you will need a service principal. You can use certificate or secret. See THIS link for the different methods. You will need to give the service principal proper access and this will depend if you are using RBAC or access policy for your key vault. So the steps you need to follow are:

1. Create a key vault and create a secret.
2. Create a Service principal or application registration. Store the clientid, clientsecret and tenantid.
3. Give the service principal proper access to the key vault(if you are using access policies) or to the specific secret(if you are using RBAC model)

The python link for the code is HERE . The code that will work for you is below:

from azure.identity import ClientSecretCredential
from azure.keyvault.secrets import SecretClient
tenantid = <your_tenant_id>
clientsecret = <your_client_secret>
clientid = <your_client_id>

my_credentials = ClientSecretCredential(tenant_id=tenantid, client_id=clientid, client_secret=clientsecret)

secret_client = SecretClient(vault_url="https://<your_keyvault_name>.vault.azure.net/", credential=my_credentials)
secret = secret_client.get_secret("<your_secret_name>")

print(secret.name)
print(secret.value)
