What is password protection?
By Mark Boreland ·
In short
- Password protection puts a password in front of a shared link, so only people who know it can open the file.
- The link looks normal; the file stays hidden until the right password is entered.
- It is the simplest way to keep a shared document from being opened by whoever finds the URL.
Password protection adds a gate to a share link. Anyone who opens the URL sees a prompt rather than the file, and only the correct password lets them through. The link itself can be pasted anywhere safely, because the contents stay sealed until someone proves they are meant to see them. It is access control reduced to its simplest useful form, one secret shared with the people who should have it.
This is the right tool when a link might travel further than you intend. A pricing proposal, a draft you share a deck with a client, or a document with personal details should not be openable by anyone who happens to receive a forwarded message. A password means the URL leaking does not mean the file leaking. It pairs well with expiring share links when you want both a lock and a deadline, so access is limited to the right people and the right window.
On NudgeHost the password is stored only as a secure hash, never as plain text, and entering the right one quietly opens the file for that visitor. Hosting is free to start, and the Pro plan carries the access controls across your files. The honest framing is that password protection is not heavy security for state secrets; it is the practical lock that stops an ordinary shared link from being opened by the wrong person.

Frequently asked questions
Where is my password stored?
Only as a secure hash, never as readable text. The file opens when a visitor enters a password that matches the hash.
Can I protect any file type?
Yes. Password protection sits in front of the link, so it works the same for a PDF, an image, an HTML page, or any other file.
What if I forget the password I set?
You can change or remove it from your dashboard at any time, which updates what visitors need to enter.
