Password Pusher
Temporary secrets get a short life with Password Pusher, which shares passwords, notes, URLs and files through one time links that expire after a set number of views or a set time. Payloads are stored encrypted with AES-GCM, a link can be protected by a passphrase, every view is recorded in an audit log, and the data is deleted once the limits are reached.
Teams use it to onboard a contractor, hand over credentials during an incident, or send a link that should not sit in a chat history for years.
Hosting it on your own server keeps those secrets and the audit trail internal, costs nothing per shared link, and reduces to a database and file directory you can snapshot.
