Share a document safely
Updated 15 November 2026 · by the DocuLock team
In short. Open a document, tap Export, then Share a secure link. Choose how long it works, how many times it opens, whether a copy may be saved, and add an access code. Send the link and the code by different routes. Revoke it any time: it stops at once.
What is ephemeral access?
Ephemeral access is access that ends on its own. An email attachment or a chat photo stays with the recipient for good. A DocuLock link works for the time you choose, opens only as many times as you allow, and stops the moment you revoke it. With saving turned off, the recipient can only view the document, not keep it.
How does a DocuLock link work?
The link holds the key to the shared copy after the #, the part of a web address that browsers never send to a server. The recipient opens it in any browser. The page decrypts the document on their device. The DocuLock service stores only the encrypted copy and counts the views.
What can I control?
| Setting | Choices |
|---|---|
| Link works for | From one hour to a date you pick |
| Can be opened | Five times by default, any number, or no limit |
| Save a copy | On or off. Off means view only. |
| Access code | A random code like 5FY-D4T, sent separately |
How do I take it back?
Open the document's details (the ⓘ button) and choose Shared links, or Settings, then Shared links. Choose Revoke. Deleting a document also ends its links.
What a link cannot do
- It cannot stop someone photographing their own screen.
- If you allow a saved copy, the copy the recipient keeps is theirs.
- It cannot protect a link and code sent through the same chat.
Tip: black out what the recipient does not need first, with Tools, then Hide.

Questions
Is it safe to send a passport scan by email?
An email attachment stays in both mailboxes indefinitely. A DocuLock link expires, can be limited to a few views, needs an access code and can be revoked.
What is ephemeral access to a document?
Access that ends on its own: a link that works for a set time or number of views, needs an access code, and can be revoked at any moment.
Can DocuLock see the documents I share?
No. The shared copy is encrypted on your phone. The key travels in the link after the #, which browsers do not send to servers.
