OTS

Share one-time secrets that self-destruct after being read once

About OTS

OTS is a free, open-source web application for sharing one-time secrets such as passwords and tokens. You enter a secret, get a link, and send it to the recipient; the secret is encrypted with AES-256 in the browser before upload and permanently deleted the first time the link is opened, so it cannot be read twice or leak later from an inbox. Self-hosted in a small Go binary, OTS suits teams and administrators who exchange credentials occasionally.
