Onetime auth burns secrets after one read

Editorial interest 81/100 Selection signal · not a rating of the site

A browser-encrypted sharing tool for passwords, complete logins, and live 2FA codes that expire or destroy themselves after a chosen number of views.

Landing page captured for the 2026-09-01 issue.

Field notes

The interface packages several login components into one disposable link, including an optional QR-image input for a 2FA seed. Senders choose both a view ceiling—1, 3, 5, 10, or 25—and an expiry window from 15 minutes to three days. The page describes the key as living in the URL fragment rather than on the server, and presents a separate management link for checking whether a share was opened or revoking it early.
