There are plenty of trustworthy providers - it just depends what you'd like to study. If you google Moocs you'll find a range of free accredited courses from around the world (including the Open University, various universities, Reed etc.).
As an example see: [
www.ed.ac.uk] - free short courses from Edinburgh university
and [
