Members area confusion, navigation link doesn't appear

Hey guys, 

I'm creating a squarespace website for a client and I'm on the final stage of creating the membership area. It's an 8 week fitness challenge. I've tried everything and I keep getting issues with it. I simply want a members area login in the navigation bar which will be password protected once someone has paid! How do I go about this? I've created the members are but it doesn't show up in the navigation bar so how is anyone supposed to be able to login? Also, when it's created do I just put a password on it myself which my client can distribute to her group or is there individual passwords created for each person when they join the members area?

Any advice or help would be much appreciated!

I recommend you take a read through the Member Areas checklist to see if you have missed any steps.

If you need assistance after reading the guide I recommend you contact Squarespace Customer Care as they'll have access to the website and can guide you more easily.

However, if you'd like more assistance from the forum community, we'll need you to provide us with a working link to the site so that we can take a look. We'll also require some screenshots of the Pages panel showing how you have configured the Member Area pages.
