How to send files without an account
The receiver needs no account: they enter your username and 4-digit PIN.
How it works
1. Create a Pinfast account and upload the file at pinfast.io or in the Pinfast app. When you upload, choose how long the file stays available: 3 hours or 24 hours.
2. Tell the receiver your username and your 4-digit PIN. You do not need to make a link for each file. Your address pinfast.io/your-username stays the same.
3. The receiver opens pinfast.io/your-username in a web browser, enters the PIN and downloads the file. They do not need to sign up or install an app.
Anyone who knows your username and PIN can open your files. Share them only with the person you are sending to, and change your PIN when you need to.
