Hi. As i seem to have understood, you can't find what password each user has in any sort of way since its runned with MD5 and so on.
I'm currently developing a system for my community and instead of having them all create an account all over again, i was wondering if i can somehow use the existing user & password from xenforo on there? I'm unsure what tables they are stored in.
If you're going to try to authenticate against the XF DB, the best approach would be to use the XenForo code/API that XF uses itself. There are different authentication schemes that can be involved so the code figures out what's needed automatically.
