Is it possible to put a password on a single landing page? Anyone successful at it?
Please move the thread to Products since this is Marketo product-specific (as opposed to general marketing topics) and I'll answer over there.
I just moved it Sanford.
OK. The answer (as also found in past Community threads) is that truly secure landing pages, with per-user passwords and security enforced on the back end, are not possible.
But a single preshared password (which seems like what you're getting at) and good-faith security on a hidden page is possible. See my answer and demo here: https://nation.marketo.com/message/153865
