In the administration section, it shows my (Amazon, FTP, etc.) passwords starred – but I want to see the actual text

We star out passwords because it prevents “shoulder-surfers” (people looking over your shoulder) from seeing the password.

Three quick, different ways that you can access your stored passwords are:

1. Press “View Source” in your web browser, and read it out of there.
2. Download a backup of the site’s database and read it out of there.
3. Install an extension in your web browser to un-star all passwords.

If you want to display passwords directly, then do this:

1. Using FTP (or equivalent) access to your web hosting space, create (if it does not already exist) a folder called mu-plugins in the content directory of your WordPress install (which is usually called wp-content – i.e. the new directory will be wp-content/mu-plugins).
2. In that folder, create a new file called ud-star-passwords.php (or anything else ending in .php) with the following content:

<?php
add_filter('updraftplus_admin_secret_field_type', 'updraftplus_admin_secret_field_type');
function updraftplus_admin_secret_field_type($type) { return 'text'; }
