Password Protect a Link
The web has no built-in password field for URLs — but three real approaches get you a gate. Here's an honest look at how each one works.
Three ways to lock a link behind a password
1. 🔐 Client-side encrypted link locks
These tools encrypt your destination URL and give you a shareable lock page plus a password. The decryption happens entirely in the recipient's browser — no server, no account, often free.
- Upside: zero setup, works for any URL, no account anywhere.
- Downside: clunky recipient experience — an unfamiliar page, and the password has to be re-entered on return visits. Because the check runs in the browser, anyone who ever obtains the original destination URL skips the gate completely.
2. 📁 Passwords on content you host
If the content lives on a platform you control, use its own protection: password-protected posts on WordPress-style sites, or password options some cloud storage services offer on shared files. The platform verifies the password before showing anything.
- Upside: managed for you, familiar to recipients, nothing extra to sign up for.
- Downside: it only covers content hosted on that platform. You can't put a Google Drive or WordPress password in front of someone else's page.
3. 🔗 Hosted password-protected short links (Sinkto.Link)
A short link with a password page in front of it. You create a link, set a password, and share the short URL. Visitors hit a password page; the correct password redirects them to the destination, which can be any URL on the web.
- Upside: one clean, consistent page for recipients; any destination URL; passwords stored hashed with guesses rate-limited to 5 attempts per 5 minutes; and after unlock the click is still tracked — country and city, device, browser, referrer, and UTM parameters.
- Downside: creating protected links requires a (free) account, because the password has to be managed server-side. We won't pretend otherwise: a no-signup "tool" here would mean faking the password check in your browser.
Quick comparison
| Client-side locks | Hosted-content passwords | Protected short links Sinkto.Link | |
|---|---|---|---|
| Works with any destination URL | ✅ Wraps any link | ❌ Only content on that platform | ✅ Any URL |
| Account needed | No | Varies by platform | Free Sinkto.Link account |
| Password handling | In the recipient's browser | Managed by the platform | Hashed, 5 attempts / 5 min |
| Recipient experience | Clunky — extra page, re-entry | Smooth inside the platform | Clean password page, one redirect |
| Analytics after unlock | ❌ | Rarely | ✅ Country/city, device, browser, referrer |
| Best for | One-off shares without an account | Content you already host | Campaigns, deliverables, team-only links |

One honest caveat
Every "gate in front" approach — including this one — protects the link you share, not the destination site itself. If the destination URL leaks through another channel, it opens directly. For genuinely sensitive material, use the access controls of the system hosting it.

Create Your Protected Link Free →Frequently Asked Questions
Can you password protect a URL for free?
Yes, three ways. Client-side link-lock tools are free and need no account, but the experience is clunky. Password features on platforms you already use (like password-protected posts) only cover content hosted there. A free Sinkto.Link account lets you put a password page in front of any destination URL, with hashed passwords and click analytics included.
How do password-protected short links work?
You create a short link and give it a password. Anyone who opens the link sees a password page instead of the destination. Once they enter the correct password, they are redirected to the real URL. The destination address never appears in the shared link itself, and the visit is still tracked in your analytics.
Are the passwords stored securely?
Sinkto.Link stores passwords hashed, never as plain text, and limits wrong guesses to 5 attempts per 5 minutes per link. One caveat applies to every shared-password approach: anyone who has the password can open the link and pass it on, so choose a password you only share with the intended audience.
Do click analytics still work on a password-protected link?
Yes. After a visitor unlocks the link, the redirect is tracked like any other click: country and city, device type, browser, referrer, and any UTM parameters attached to the link. You can also deactivate the link entirely when the campaign or share window ends.
What's the difference between a client-side lock and a hosted password page?
A client-side lock does all its work in the recipient's browser — no server or account needed, but recipients face an extra decryption page and must re-enter the password, and anyone holding the original destination URL bypasses the gate entirely. A hosted password page (like Sinkto.Link's) verifies the password server-side before redirecting, giving one consistent, branded experience.
Can I password protect a link to someone else's website?
You cannot add a password to a site you don't control — hosting-based password features only protect content on that platform. What you can do is gate access through a short link: put a password page in front of any destination URL with a free Sinkto.Link account. Just remember it protects the short link, not the destination site itself.
