A lot of "free" file sharing quietly becomes account sharing. The sender is asked to verify an email, and then the recipient lands on a page that pushes them to register before downloading. Enzonic Send keeps both sides out of that. This page is about the receiving end, about what you avoid by not logging in, and about using shared or public computers safely.
If you are mainly interested in sending without creating an account, start with Send Files Without Signing Up. The short version: up to 500 MB per transfer with no account, 2 GB with a free one.
The recipient never sees a sign-in screen
This is the part people underestimate. When you send a file, the person on the other end might be a client, a relative, or someone at a print shop. Any extra step on their side costs you time, usually in the form of a follow-up message asking how to get the file.
With Enzonic Send, the receiver has three ways in, and none of them involve an account:
- The link. They click it and download.
- The QR code. They point a phone camera at your screen, open the link, and download.
- The 6-digit code. They go to send.enzonic.com/receive, type the six digits, and download.
If you set a password, they type that too. That is the whole process. There is no "create an account to continue" prompt, no trial offer, and no requirement to install the mobile app, although the app can scan codes if they prefer it.
Why not logging in is a privacy decision
Every login you perform leaves something behind: a session cookie, a saved password prompt, a record in your account's activity log, sometimes an email address in a marketing list. For a one-time transfer, none of that is necessary.
Not logging in means:
- No identity attached to the transfer. The service holds the files and your chosen options, and that is it. Nobody asks for your name or your recipient's email address.
- No mailing list. You cannot be added to one if you never handed over an address.
- Nothing to forget to sign out of. The single most common mistake on a shared computer is leaving an email or cloud account signed in. If you never sign in, you cannot make that mistake.
To be clear about what this does not mean: the files themselves are stored on Cloudflare's network until they expire or you delete them. They are encrypted in transit (TLS) and at rest, but Enzonic Send is not end-to-end encrypted. Skipping the login protects your accounts; a password on the transfer protects the files. See password-protected file sharing.
Shared, public, and borrowed computers
Library PCs, hotel business centers, school labs, a print shop terminal, a colleague's laptop. These are exactly the places where you should avoid typing your email or cloud storage password, and also the places where you often need a file.
Getting a file onto a public computer
- On your own phone, open send.enzonic.com and upload the file.
- On the public computer, open a browser and go to send.enzonic.com/receive.
- Type the 6-digit code shown on your phone and download.
No account touched the public machine. The code is short enough to type from memory, which is far easier than typing a long link. More on this in sharing files with a 6-digit code.
Getting a file off a public computer
Reverse the direction. Upload from the public computer, then scan the QR code with your phone camera. The file goes to your phone without you entering anything on the shared machine. Phone to laptop transfers cover both directions in more depth.
Before you walk away: a checklist
- Delete the downloaded file from the Downloads folder, and empty the recycle bin if you are allowed to.
- Close the browser fully, or use a private/incognito window from the start.
- If you uploaded something, delete the transfer once the other person has it, or choose the 1-hour expiry so it disappears on its own.
- Set a download limit of 1 if only one person should ever get the file.
How this compares to login-based options
Many familiar ways of moving files depend on an account somewhere.
| Method | Sender logs in | Receiver logs in |
|---|---|---|
| Emailing it to yourself | Yes, into your email | Yes, into your email |
| Cloud drive share link | Yes | Depends on sharing settings |
| Dropbox Transfer | Yes, needs a Dropbox account | Check their current terms |
| Enzonic Send, under 500 MB | No | No |
| Enzonic Send, 500 MB to 2 GB | Free account | No |
Emailing a file to yourself is the classic public-computer trap, because you have to sign into your inbox on that machine. Email also caps attachments; see files too big for email.
Where this approach has limits
Being honest about the trade-offs:
- 500 MB per transfer without an account. Bigger files need a free account, up to 2 GB.
- Short lifetimes. Anonymous transfers last 1 hour, 1 day or 3 days. That is good for privacy, less good if the recipient is slow.
- Anyone with the link or code can download. Without a login, possession of the link or code is the access. Use a password, a download limit, or a short expiry when that matters. Our guide to expiring file links explains how to combine them.
FAQ
Does the person receiving my files need to log in?
No. Receivers open the share link, scan the QR code, or enter the 6-digit code at send.enzonic.com/receive and download directly. There is no account option on the receiving side to get in the way.
Is it safe to use Enzonic Send on a library or hotel computer?
It is a reasonable choice because you never type a password into that machine. Still delete the downloaded file and the browser history when you are done, since the computer itself may not be trustworthy.
If I do not log in, what does Enzonic Send know about my transfer?
It stores the files and the options you chose, such as expiry, password and download limit, until the transfer expires or you delete it. It does not ask for your name or email.
Can I print a file from a public computer without logging into my email?
Yes. Upload the file from your phone, then type the 6-digit code on the public computer at send.enzonic.com/receive, download it and print it.
Are files encrypted if nobody logs in?
Files are encrypted in transit with TLS and encrypted at rest. Enzonic Send is not end-to-end encrypted, so add a password for anything sensitive.
