Hi Jason.Dalton, CodeyLC, Tensitz, onepixeldeep
Could you please email contact@allegorithmic.com with info on the browser you use and its version and if you have seen a particular message in the console of your browser while trying to login?
I would also need to know how many special caracters you use in your password, and would rather not talk about that on the forum

I'll try to find where this problem is coming from, and why it is only happenning on the Substance Source platform!
Thank you
