sclogin doesn't appear in my page module manager

Djamel,
I'm unsure what you mean. Can you check the Extensions Manager in Joomla and see if it's listed there? If so, in the Module Manager, try clicking the "New" button and creating a new instance of the SCLogin module.

I hope that helps,
Alex

Glad to hear that got you going. Should you need anything else, just let us know.

Finally, if you haven't already, please consider leaving a rating and review for SCLogin, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:

Thanks,
Alex
