You don't need to log in if you simply want to browse Moodle Docs.
However, if you would like to contribute to improving the documentation, you will need to log in to edit pages.
You can log in using the same username and password as you use on moodle.org. If you don't yet have a moodle.org account, please fill out a new account form with your details.
If you created a moodle.org account previously by logging in using your Google or Microsoft account, we will need to convert your account into one with a username and password. Please contact us via the Moodle.com contact form.
