Lock a page behind a passphrase

A page only the people you trust can read — and Lanlan itself never has a copy of the contents.

What you'll get

A normal-looking page on your site that asks for a passphrase before it shows anything.
Content (a letter, an invitation, a private note) that opens only when someone enters the right phrase.
A page where Lanlan itself never sees what's inside — only an encrypted version of your text. If our database leaked tomorrow, your sealed page would still be sealed.

Good for: a card for one specific person, a sealed letter to a friend, a quiet announcement only your team should see, a save-the-date with details you don't want public.

Not good for: anything you'll need to edit on the fly, anything that should be searchable, anything you'd want shown in your pages list. Sealed pages are static and one-shot — make one, share it, done.

Make a sealed page

Tell Claude what you want to seal, where it should live, and what the passphrase is. Be specific:

"Make a sealed page at /letter that opens with the phrase 'sunset bridge 2024'. The content is: [paste the letter]."
"Create a private invitation at /party. Phrase is 'we eat at 7'. Show the date, the address, and the dress code [...]."

Claude makes the page and gives you the URL. Send the URL and the phrase to whoever should read it — by text, in person, on a postcard. Anything that's not the same email thread the URL went out in, so the two halves don't end up in the same inbox.

A few things to know about the phrase

The phrase is case-insensitive, and leading or trailing spaces are ignored. "Sunset Bridge 2024" and "sunset bridge 2024" and " SUNSET BRIDGE 2024 " all work.
The phrase is not stored anywhere. Lanlan does not have a copy. If you forget it, the content is gone — really gone, not retrievable by us. Write it down somewhere safe before you move on.
Pick a phrase the recipient already knows, or one you can tell them out-of-band: a shared in-joke, a date you both remember, a place that means something. Not "password123", but also not so cryptic the recipient can't type it back.

Change or replace a sealed page

Sealed pages don't show up in the dashboard editor — there's nothing for it to read. If you want to change the content, ask Claude to seal it again at the same path:

"Update the sealed page at /letter — same phrase, new content: [...]."

The new sealed version replaces the old one. To change the phrase too, say so.

If something doesn't work

"My recipient says the phrase doesn't work." Confirm with them what they're typing. Most failures are typos — the phrase ignores case and spaces but the spelling has to match.
"I forgot the phrase." It's gone. Make a new sealed page with a phrase you'll remember this time, and write it down.
"The page won't unlock even though I'm sure I'm typing the right phrase." Reload the page. If it still doesn't work, ask Claude to seal it again — a stray character can creep into either the phrase or the content during paste.

What to try next

If you get stuck

Ask Claude. "I can't figure out how to…" almost always gets you unstuck. For anything Claude can't help with, email support.
