Docs feedback: How do you use an access token?

RE the access token docs (https://docs.gitlab.com/ee/user/profile/personal_access_tokens.html) The page says "You can also use personal access tokens with Git to authenticate over HTTP or SSH"

But... how? The docs are pretty clear on how you make an access token. But they don't tell you what to do with one when you've got it.

(They're fairly clear on how to use it with the API. But how do you use it with http?, or with ssh?)

(I looked at the two-factor authentication page and it has the same problem. It says "When [...] you must use a personal access token instead". But they don't say how.)
