Event description
The runtime determined that one or more secrets loaded by the host aren't highly identifiable secrets. Highly identifiable secrets are preferred because they include a signature/checksum along with a prefix that enables automated scanning tools to identify the secret as an Azure Functions key value. This identifiability aids in the remediation of inadvertently leaked secrets, such as when they get accidentally checked into a source control repository.
By default, the secret key values generated by Azure Functions are highly identifiable. However, function apps that were created long ago might still have legacy nonidentifiable key values generated before highly identifiable secret generation was enabled.
How to resolve the event
This event indicates the name and type of the key that is in violation. You should regenerate the key to obtain a new value that is highly identifiable. To learn how to regenerate keys, see Renew access keys.
When to suppress the event
This event shouldn't be suppressed.
