Description

Enter your email address, and send you an email with a magic link to login without a password.

Login

• Login with email address only.
• Only registered users can login.
• Password-less login from the magic link notified in the email.
• shortcode : [magic_login]
• action hook : do_action( 'magic_email_send', $emails | array, true | bool ) : To send the magic link simultaneously from the management account.

Thanks

• This plugin is a modified version of Passwordless Login.
• The main changes are the addition of various filter hooks and the addition of the following action hooks.

Action hook

• This is for sending bulk e-mails with a magic link for login to multiple accounts from the management screen.
• When using this action hook, the URL of the page where the shortcode [magic_login] is placed should be specified in the filter hook ‘magic_login_mail_url’.

 * @param bool   true  Output notifications to the management screen immediately after sending.
