One-time or limited views
Choose how many times a link can be opened. After the final allowed view, the encrypted copy is destroyed.
Expires on your schedule
Set an expiry from minutes to days so old links stop working automatically.
Safe against link scanners
The secret is fetched only after the recipient intentionally clicks Reveal, so preview bots cannot consume it.
Password and PIN protection
Add a separate password or numeric PIN for another layer of protection when sharing sensitive access details.
You stay in control
Use the private management link to check status, disable, or destroy a secret before it is opened.
