WP Magic Link Login can be set up to display only the magic link form and hide the default WordPress Login Form. There can be situations when your WP_MAIL/SMTP functionality is not working properly (for example, using on a local machine and not sending emails, or using on a shared server that has the IP address in Black List for spamming). For this situation, we’ve added an option to force display the WordPress Default Login Form. You have to add the show_login_form parameter to the url. For example: https://my-awesome-url.tld/login?show_login_form=1 and this will solve your issue.
