Can I make my wiki password protected? How do I invite users and give them the invite key?

First, when you set up your wiki, you can choose to make it private. Do so. If you've already created it, go into "Settings" and then "Public/Private" and change the setting there.

Then, go to "Keys and Access" and set up the Invite Key. From there, you can give that password to your coworkers, and only people who have that password will be able to get in. No one else will, unless they have access to the password, which is why this option is fairly insecure.

However, if you have each of your office mates create a PBwiki Account (direct them to my.pbwiki.com), and you as the Admin invite them to the wiki by going to "Settings" and then "Users" and entering each of their email addresses, they won't even have to have the password, but they will still have access, and FOR REAL no one else will. This is the best way to do things on your end, because it makes it easy for you to add more users to your wiki when you hire more people, and if someone leaves, all you have to do is remove their account from your wiki, you don't have tho change the password every time.
