+# Authentication: Azure
+You can use the DSV web UI or the DSV cli to configure authentication using Azure.
+For this doc we will use the DSV cli.
+
+Run <br />
+`dsv config auth-provider search -e yaml` 
+<br />
+to see all of your current authentication providers.
+
+Initially, the only authentication provider is Thycotic One, similar to this:
+```
+created: "2019-11-11T20:29:20Z"
+createdBy: users:thy-one:admin@company.com
+id: xxxxxxxxxxxxxxxxxxxx
+lastModified: "2020-05-18T03:58:15Z"
+lastModifiedBy: users:thy-one:admin@company.com
+name: thy-one
+properties:
+ baseUri: https://login.thycotic.com/
+ clientId: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
+ clientSecret: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
+type: thycoticone
+version: "0"
+```
+
+## Azure Authentication Provider
+
+To add an Azure account to act as an authentication provider:<br />
+`dsv config auth-provider create --name <name> --type azure --azure-tenant-id <Azure tenant ID>`
+where:
+
+* name is the friendly name used in DSV to reference this provider
+* type is the authentication provider type; in this case, azure
+* the property flag for Azure is `--azure-tenant-id`
+
+To view the resulting addition to the config file, you would use:<br />
+`dsv config auth-provider <name> read -e yaml` <br />
+where the example name we will use here is azure-prod
+
+The readout would look similar to this:
+```
+created: "2019-11-12T18:34:49Z"
+createdBy: users:thy-one:admin@company.com
+-id: xxxxxxxxxxxxxxxxxxxxx
+lastModified: "2020-05-18T03:58:15Z"
+lastModifiedBy: users:thy-one:admin@company.com
+name: azure-prod
+properties:
+ tenantId: xxxxxxxxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
+type: azure
+version: "0"
+```
+## Azure User Assigned MSI Example
+
+First you will need to configure the User that corresponds to an [Azure User Assigned MSI](https://docs.microsoft.com/en-us/azure/active-directory/managed-identities-azure-resources/overview).
+The username is a friendly name within DSV. It does not have to match the MSI username, but the provider must match the resource id of the MSI in Azure.<br />
+`dsv user create --username test-api --provider azure-prod --external-id /subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourcegroups/build/providers/Microsoft.ManagedIdentity/userAssignedIdentities/test-api`<br />
+
