-### Configuring Unique Alternate Keys
-
-Unique Alternate Keys are properties that must be used to identify the profile, such as email, phone number, and document number. When defined, these properties can be used as the `key` parameter to retrieve and manage information from the Profile System API.
-
-This property must be structured as a string or as an array. The `v-unique-alternate-keys` array accepts up to three items, meaning three different keys. **Once created, alternate keys cannot be removed**.
-
-**Example**
-
-```json
-`v-unique-alternate-keys`: [
-    {
-        "name": "email",
-        "fields": ["email"]
-    },
-    {
-        "name": "phone",
-        "fields": ["phone"]
-    }
-]
-```

 ### Configuring TTL
 
 The TTL (Time To Live) property is a value expressed in days used to schedule the deletion of the document in the future. When this time expires, the document is automatically deleted.
