    @Rajesh Swarnkar Welcome to Microsoft Q&A, thank you for posting your here!!

    Azure Storage Accounts do not have an option for anonymous write access to blobs and containers.

    Azure Storage enforces authentication and authorization to ensure that only authorized users or applications can write to the storage account.

    To interact with an Azure Storage Account, users or applications typically need to provide valid authentication credentials, such as storage account keys, shared access signatures (SAS tokens), or Azure Active Directory (Azure AD) credentials, RBAC roles.

    However, you can configure specific access policies to grant limited, time-bound, and fine-grained access to containers and objects within a storage account by using shared access signatures (SAS). With SAS, you can provide temporary access to users or applications without exposing your account keys. You can control the permissions granted in the SAS token, including read, write, delete, and list operations.
