I would like to pick up this issue

[ldez]

Hello,

the sentence inside the doc seems correct: the goal is to restrict access to only known users and not unknown users.

[sssash18]

I think the word restricts makes the sentence little ambiguous . It would be better if we replace it with limits.

[geraldcroes]

The sentence is indeed correct, but I can understand that it can sound ambiguous to some.

We could rephrase with something like

The DigestAuth middleware grants access to services to authorized users only.

If we decide to do so, we need to rephrase for the BasicAuth middleware as well.

@sssash18, feel free to propose changes and create a PR
