Hi,
In order to modify the email notification we will need to use some custom code:
1. Create an empty plugin like this: https://gist.github.com/sareiodata/76f701e01db6685829db
2. Add the following code to the end of it:
/*
* Filter to modify the email notification sent to the user by Passwordless Login add-on
*/
add_filter ( 'wpa_email_message', 'wppbc_change_email_notifcation_paswordless_login', 20, 2 );
function wppbc_change_email_notifcation_paswordless_login($content, $url){
$blog_name = get_bloginfo( 'name' );
$message = sprintf("Login to $blog_name by visiting this url: $url - My Custom text" , $url );
return $message;
}
3. Replace My custom text with your custom text
4. Install this plugin via FTP (copy it inside wp-content/plugins) or create a zip archive with it and install it via the WordPress plugin upload functionality
Test it out and let me know if it works.
Best regards,
