You have the ability to add a specific Login Form Mergecode to any page or post which will insert the login form.
Login Form Mergecode: [wlm_loginform]
Adding that mergecode to the content section of a page or post will insert a login form.
Note: This does not need to be added to the HTML of a page or post. It can simply be added to the content area.
There is also a Mergecode and Shortcode insert option that appears on Pages and Posts when using the WordPress Gutenberg editor. (Another option to generate and copy a shortcode or merge code is the Shortcode Creator found on the WishList Member Dashboard)

The blue WishList Member code inserter icon appears on the Classic Block of the Gutenberg editor and can be used to add mergecodes and shortcodes to a page or post.
More details on specific Mergecodes and Shortcodes is explained in this Knowledge Base article.
