### Proposed topic or title Credential reuse ### Location in table of contents. To be added under the Authentication ToC node at https://learn.microsoft.com/dotnet/azure/sdk/authentication/ ### Reason for the article The XML docs for our credentials recommend reusing credentials; however, there are no details on the how or the why. See https://github.com/Azure/azure-sdk-for-net/blob/985aff3df6ca7b073d4a95cf153d485d19bcda87/sdk/identity/Azure.Identity/src/Credentials/DefaultAzureCredential.cs#L104-L107. By documenting this guidance, we help customers bypass discovery each time and use the token cache. ### Article abstract TBD ### Relevant searches _No response_
