All requests to a search service need a read-only api-key that was generated specifically for your service. The api-key is the sole mechanism for authenticating access to your search service endpoint and must be included on every request. In REST solutions, the api-key is typically specified in a request header. In .NET solutions, a key is often specified as a configuration setting and then passed as Credentials (admin key) or SearchCredentials (query key) on SearchServiceClient.

Keys are created with your search service during service provisioning. You can view and obtain key values in the Azure portal.
What is an api-key
Two admin keys are created for each service so that you can rotate a primary key, using the secondary key for business continuity. In the Settings Keys page, copy the secondary key. For all applications, update the api-key settings to use the secondary key. Regenerate the primary key. Update all applications to use the new primary key. Jun 08, 2018 When you’re working with a single MySQL database, you can simply use an auto-increment ID as the primary key, But this won’t work in a sharded MySQL database. So I looked at various existing solutions for this, and finally wrote a simple 64-bit unique ID generator that was inspired by a similar service by Twitter called Twitter snowflake. AUTO INCREMENT Field. Auto-increment allows a unique number to be generated automatically when a new record is inserted into a table. Often this is the primary key field that we would like to be created automatically every time a new record is inserted. I want to know if composite primary keys is a bad practice and if not, on which scenarios is recommendable to use. ID auto-generated field as the primary key.

An api-key is a string composed of randomly generated numbers and letters. Through role-based permissions, you can delete or read the keys, but you can't replace a key with a user-defined password or use Active Directory as the primary authentication methodology for accessing search operations.
Two types of keys are used to access your search service: admin (read-write) and query (read-only).
Visually, there is no distinction between an admin key or query key. Both keys are strings composed of 32 randomly generated alpha-numeric characters. If you lose track of what type of key is specified in your application, you can check the key values in the portal or use the REST API to return the value and key type.
Note
It is considered a poor security practice to pass sensitive data such as an
api-key in the request URI. For this reason, Azure Cognitive Search only accepts a query key as an api-key in the query string, and you should avoid doing so unless the contents of your index should be publicly available. As a general rule, we recommend passing your api-key as a request header.
Find existing keys
You can obtain access keys in the portal or through the Management REST API. For more information, see Manage admin and query api-keys.

Create query keys
Query keys are used for read-only access to documents within an index for operations targeting a documents collection. Search, filter, and suggestion queries are all operations that take a query key. Any read-only operation that returns system data or object definitions, such as an index definition or indexer status, requires an admin key.
Restricting access and operations in client apps is essential to safeguarding the search assets on your service. Always use a query key rather than an admin key for any query originating from a client app. https://yellowforms564.weebly.com/blog/days-gone-cd-key-serial-generator-pc-download-google.

Note
A code example showing query key usage can be found in Query an Azure Cognitive Search index in C#.
Regenerate admin keys
Two admin keys are created for each service so that you can rotate a primary key, using the secondary key for business continuity.
If you inadvertently regenerate both keys at the same time, all client requests using those keys will fail with HTTP 403 Forbidden. However, content is not deleted and you are not locked out permanently.
You can still access the service through the portal or the management layer (REST API, PowerShell, or Azure Resource Manager). Management functions are operative through a subscription ID not a service api-key, and thus still available even if your api-keys are not.
After you create new keys via portal or management layer, access is restored to your content (indexes, indexers, data sources, synonym maps) once you have the new keys and provide those keys on requests.
Secure api-keys
Key security is ensured by restricting access via the portal or Resource Manager interfaces (PowerShell or command-line interface). As noted, subscription administrators can view and regenerate all api-keys. As a precaution, review role assignments to understand who has access to the admin keys.
Members of the following roles can view and regenerate keys: Owner, Contributor, Search Service Contributors

For identity-based access over search results, you can create security filters to trim results by identity, removing documents for which the requestor should not have access. For more information, see Security filters and Secure with Active Directory.
