What do you do to safely share a file from the cloud (OneDrive, Google Drive, DropBox, etc.) ?

Do you share the password in the same email that shares the link to the file? Hopefully not, but how do you share the password then? By another email? That's still the same medium. SMS by phone, perhaps? Other?

How do you safeguard your other files in the cloud? Do you blindly trust your cloud provider? Or do you only have that one file in your entire cloud that you only leave there for 24 hours? Or do you perhaps encrypt the file with its own password? So, 2 passwords to get at the content of the file, one to download the file and a second one to open the file?

Enquiring minds want to know :)

Well, this anser really requires a very extensive answer. Too many factors nowadays. Best way to pass files is to either run through a VPN or through the Tor Browser for anonimity and security. Outside of that if you know the person you are sending something to, text them from your phone the password and make something like an encrypted RAR file, send the file boom all good. Just opinions and ideas for you.

I've only shared a picture folder with family. I told them over the phone what the password was. I do have a few files in my Personal Vault on OneDrive. When I want to open it, MS sends me a code to my email.

That's all I ever use cloud for anyway - sharing, whether between devices and/or between people. NEVER as a backup destination.

I upload and remove contents directly through the website(s). I never have any cloud software installed (too many posts on multiple forums about indiscriminate random software changes that have resulted in users losing data)

I know there is highly encrypted and secure ways to share files through sites but I am not in the business field anymore as of 7 years ago so I couldnt even tell you what types of sites or services there are. I just know there are quite a few out there though.

for G-Drive, Create a separate folder for sharing and add the email address of the people you want to share it with. They will only have access to that folder. Just move everything you want to share in there.
I do the same on my personal cloud (Qnap NAS). I have a separate folder for sharing with access control.

Please feel free to provide an as extensive answer as you like :cool:

We are all looking forward to it :cool::cool:
Well extensive is only as extensive as one would be able to understand in this case. So first, how tech savvy are you?

Well, I would say that most of the regulars here are above average, and some of us here are at the esoteric level.

Vast majority of user loss of data on reputable cloud services is PEBCAK!

I use Microsoft OneDrive from my Office 365 subscription. When I want to share something with somebody I usually just put it into it's own folder and then you simply right click on the folder and you get a link and you can give them read-only or edit capabilties Easy Peasy. They only have access to that folder.

Hm ... no follow up from our friend @imanlien2020

Or was it an individual invitation to me? Well, no, I would not go it alone. But I am eager to go it with a (smallish) herd of knowledgeable and equally eager people to explore the subject matter in the OP.

Hm ... I feared worse with the required 'tech savvy' :) The links aren't that bad :)

About the file sharing sites in second link being more secure than the ones in the first link, in what way are the former sites more secure than OneDrive and Google Drive, for example?

And yes, I have dabbled with Tor, I have a free VPN, and I very, very occasionally run Tor over VPN, just to see if it still works. It is not so much privacy that is my concern, it is security, i.e. I don't want a file/info to fall in the wrong hands, but I also don't want the security overhead to become so big that the tool(s) becomes impractical to use. A good example is Adobe technology that is very secure, but also very complex, and nobody uses it (the sender may have studied the technology, but the average recipient throws up his hands and says, send me a fax)

I have dabbled with the things that I mentioned in the OP, I wonder if there are better things out there.

Absolutely. You know how to use and control it. I know how to control and use it (but don't ... simply because I can't be bothered jumping through all the settings hoops).

But because it's offered to the users, "in your face", so many people just click and/or don't bother to check the settings. That's when the trouble starts.

As per info posted to this thread, the simplest file sharing from the cloud is via OneDrive > put the file in folder > right-click the folder > share the URL of the folder (contains a 39 long string of random characters) via email.

If you need more security, slap on a password that you can share via the phone with a voice message or SMS.

I will mark this thread 'Solved', thanks to all who responded (y)

They only have access to that folder.

I just share simple files from my OneDrive. The user with a link can ONLY download the shared file, nothing else, nor do they have access to any other files on my OneDrive.

Of course, the user wanting to download the shared file needs a Microsoft account, to sign in to OneDrive to be able to start download. But that's it; I really do not need set any passwords.

An example: anyone wanting the latest Dev and Beta build Insider ISO, build 22581.1 (23-MAR-2022) in UK or US English, can download it from my OneDrive. No password required:

EN-GB:

Download

EN-US:

Download

These ISO images contain following editions:

22581.1.jpg

Any user clicking the links will only see this:

Dev Build 22581.1 ISO.jpg

They have no way to see / download anything else from my OneDrive.

Safe & secure. OneDrive to win!

Well, the access control provides for setting an optional password for good reason, e.g. to restrict access to only the person with the password.

It is an additional security measure available on OneDrive (and other cloud services)

My point was, that when sharing something that I do not care if it will be reshared further by the person getting my link, no password is required. Yet, me sharing the link is completely safe from my point of view: anyone with the link cannot see / download / edit anything else on my OneDrive.

Well, you care only about one aspect of info security, you might as well put the link up on a website instead of on OneDrive.

Others may care about who can access their info, e.g. photos of a family vacation with teenage daughters at the beach, for family eyes only.

That's a different aspect of info security, and that's where passwords come in handy on OneDrive (and even that is not really secure, depending on how recipients handle the password)

It is for this and other reasons that I put in the word 'safe' in the thread title, it is a very BIG topic as one poster said, but the thread ran its course without really doing justice to the word.
