Why passcodes beat raw links

Raw links leak. SSO walls repel.

A forwarded URL is an open door; an enterprise login wall is a slammed one. A passcode is the handshake in between.

Slack & email forward everything

Links get pasted into channels, forwarded to assistants, and screenshotted into decks. A passcode means the URL alone opens nothing — the secret travels separately.

Enterprise SSO alienates clients

“Sign in with your work account” kills deals. External clients, candidates, and partners should not need your identity provider to view a proposal.

One code, every device

A 4–8 character passcode works on any phone in seconds — no app install, no password manager, no IT ticket. Security people can actually get.

Made for confidential sharing

Lock it like the pros do

Proposals, prototypes, contracts, and guest lists — every sensitive share, one passcode away.

Freelancers & agencies

Client proposals & pricing quotes

Send quotes competitors would love to see — behind a code only your client knows. Rotate the passcode when the deal closes so forwarded links go dark.

Founders & product

Unreleased demos & prototypes

Share Figma prototypes, staging links, and beta dashboards under NDA-friendly gates. No login friction for testers and investors.

Legal & financial documents

Tax returns, contracts, and cap tables deserve better than an open Drive link. Add 24-hour expiry for truly sensitive drops.

Private events & VIP RSVPs

Keep guest lists private with locked invitations and QR codes at the door — only invited guests with the code get in.

How it works

Locked in four steps

From sensitive to shareable in under a minute.

1. Paste link or upload file

Any URL — or a PDF, HTML, or ZIP up to 50MB. No signup.

2. Set your secret passcode

4–8 characters of your choice, or one click for a random secure key.

3. Copy your locked URL

Share drops.sh/l/vault-… plus the code — or print its QR.

4. Recipient enters PIN

A branded lock screen, one tap, no account. Destination opens instantly.

Free utility

Share secrets like links, guard them like vaults

Convenience for recipients, control for you.

To password-protect a link free is to solve the oldest sharing dilemma: the easier a link is to open, the easier it is to leak. Drops splits the difference — the URL travels anywhere links travel, while a short passcode travels separately to the people you trust. Intercept one without the other and there is nothing to see.

Whether you want to lock a URL with a password for a client prototype, share a password-protected link to a financial report, or create a secure link with a PIN for a VIP event, the locker above does it in seconds: paste, set code, share. Add a 24-hour fuse for flash shares, or keep the link permanent — and share a private link free without ever asking recipients to create an account.

Need the full arsenal? Gate entire sites with website password protection, bundle sensitive files in a secure data room, serve retainer clients through a client portal, and watch every unlock with document tracking.

FAQ

Locked-link questions, answered

Accounts, revocation, encryption, limits, and expiry.

No. Recipients open your locked link, enter the passcode you shared, and see the destination — no signup, no download, no enterprise login. That is the core advantage over Drive and SharePoint permission walls when sharing outside your organization.
Yes. Claimed links let you rotate the passcode, set a new expiry, or revoke access entirely — instantly, without changing the URL you already sent. If a contractor engagement ends or a quote goes stale, one click shuts the door.
Locked links are served over HTTPS on the global CDN, and the destination stays hidden until the correct passcode is entered — intercepting the URL alone reveals nothing. For regulated or highly sensitive material, pair the passcode with short expiries and unlock tracking on a claimed account.
The generator above is free forever with no credit card — lock demo links and share them immediately. A free Drops account raises the limits, keeps links permanent, and adds unlock analytics and custom-domain branding. No per-link fees, ever.
Yes. Choose 24-hour expiry for flash shares, 7 days for weekly reviews, or permanent hosting with a free account. For collections of expiring files, see the secure data room.
Any URL — Figma prototypes, unlisted videos, dashboards, Google Docs, Notion pages — or an uploaded PDF, HTML file, or ZIP. The lock screen stays the same sleek branded experience either way, and you can attach a QR code for print or in-person sharing.
ZIP passwords force recipients to download, find extraction software, and type cryptic strings — miserable on phones. A Drops locked link unlocks in one tap in the browser with a friendly PIN pad, works on any device, and gives you expiry plus unlock tracking that a ZIP file never can.
Yes. Create a free account and every unlock is tracked — when and where — so you know the moment a client opens your proposal. For deeper per-viewer analytics, add document tracking.
