.. _-authenticateBasicPFAsync-java-:

authenticateBasicPFAsync
========================
Wraps the inner route with Http Basic authentication support using a given ``AsyncAuthenticatorPF<T>``.

Description
-----------
Provides support for handling `HTTP Basic Authentication`_.

Refer to :ref:`-authenticateBasic-java-` for a detailed description of this directive.

Its semantics are equivalent to ``authenticateBasicPF`` 's, where not handling a case in the Partial Function (PF)
leaves the request to be rejected with a :class:`AuthenticationFailedRejection` rejection.

See :ref:`credentials-and-timing-attacks-java` for details about verifying the secret.

.. warning::
  Make sure to use basic authentication only over SSL/TLS because credentials are transferred in plaintext.
