The Share Link You Forgot to Expire

You meant a loan. You published a key.

The contractor finished. The link still works. Search, Slack logs, and forwarded mail still have it.

Public-link culture trained us to treat URLs as disposable. They are not.

From the record

If you would not leave a house key under the mat for a year, do not leave a tax PDF URL under the mat for a year.

GUIDEORA rule for share links

Three knobs, in order

Named accounts first. Password second. Expiry third. View-only if the product has it. Do not put the password in the same email as the link.

• Audit old shares twice a year.
• Client-side encrypted shares still fail if the URL plus password sat in one thread.
• Google-style 'anyone with the link' is convenience. Treat it as public.
• Version history will not save you if the leak was a copy they already downloaded.

Proton Drive's share story

Proton Drive currently lets you add password and expiry on links as they document it, on top of E2E file encryption. That is why it is the example: the knobs match the job. Confirm the live share UI. It is still a URL.

A free 5 GB plan may be enough to practice one serious share. Checkout wins on paid.

End the loan

Set expiry. Then delete the share. Proton Drive is the knob example this site uses. GUIDEORA does not host your PDF.
