private pages and access - not working

[LeahBS]

Hi there

I have created a download page that takes my clients from pay pal to a complimentary download - however, existing clients who I want to give the same downloads to are unable to access this page.

I have set 'no follow' and 'no index' as I don't want google to take any notice of the page and I want to keep it hidden.

I also set it as private - is that why people cant access this from the url link?

Is it enough to simply add 'no follow' and 'no index' to ensure people wont find my downloads?

If I were to set the page to require a password - how does that work with wordpress - do I provide the password? Does this happen automatically?

Is there a better way to set this up?

Much appreciate your help
