Check access before sharing a work document

The short answer: Link sharing is convenient but can turn a targeted exchange into possession by anyone who receives a forwarded URL. Default permissions often persist long after a project ends.

Link convenience can widen access beyond the recipient

The useful move is to separate what the claimant controls from evidence you can obtain independently. Names, logos, caller ID, screenshots and a polished page can all be copied. A saved telephone number, a typed official address, a known colleague or a protected transaction route changes the channel instead of merely inspecting the same claim again.

Risk also depends on consequence. Reading a public page is different from granting remote access, sending an identity document or approving an irreversible payment. As the cost of error rises, require stronger verification and prefer a step you can undo.

Warning signals to assess together

These clues become useful when they form a pattern. Treat each one as a prompt to verify, not as a verdict by itself.

• The link works without sign-in when identity matters

  Pair this observation with a separate check: Classify the document before sharing.

• Editors can invite others without review

  Pair this observation with a separate check: Use named recipients and least privilege.

• No owner is responsible for removing access

  Pair this observation with a separate check: Set an expiry or schedule an access review.

Do not use one clue as a verdict: A restricted link protects distribution, not what an authorised recipient does after downloading the file.

Set least privilege before sharing the document

Keep the verification route separate from any contact detail or instruction supplied in the questionable message.

• Classify the document before sharing

  This step tests the related concern: The link works without sign-in when identity matters.

• Use named recipients and least privilege

  This step tests the related concern: Editors can invite others without review.

• Set an expiry or schedule an access review

  This step tests the related concern: No owner is responsible for removing access.

For a structured settings review, the privacy settings planner can turn broad concerns into a short list of account checks.

Decide what to do after verification

If the independent channel confirms the identity and request, ask whether the proposed method still gives you a record and recourse. Legitimate people and organisations should tolerate a proportionate verification step. Resistance, secrecy or a demand to bypass normal controls is new evidence, not an inconvenience to ignore.

If the evidence remains mixed, reduce exposure: do not send original documents when a redacted copy is enough, do not pay a deposit before verifying authority, and do not approve access broader than the task requires. “Not yet” is a valid decision when the missing fact matters.

The same independent-channel principle is applied in the least-privilege app permissions guide to a different professional request.

What this verification cannot establish

This guide cannot authenticate a specific person, account, website or transaction. Interfaces and attack methods change, and legitimate situations sometimes contain unusual details. For an active loss, account compromise or safety threat, contact the relevant institution or official reporting service through a verified route.
