I have registered via social network (Facebook / Google). How do I create a login/password entry point instead?

Please, go to your User Office at https://my.keepsolid.com. Log in with Google/Facebook account (this option is below 'Forgot password?'). Click on your KeepSolid ID at the top right and select Set Password (Create a new password for your account). This way you will be able to login without using Google/Facebook account. You will need to enter your email and the password you've created.
