Think about the last time you used a computer that wasn't yours: a college lab PC, a community library desktop, a machine at your Work Experience placement. If you signed into your school email or cloud drive and walked off without signing out, the next person in that seat had a door into your account. Today you'll learn the small set of checks that keep your work safe on any shared machine, while still getting the benefit of working across computers.
You finish a shift at your Work Experience placement. Your supervisor's PC is still signed into your personal school OneDrive. You're in a rush, so you close the browser tab and leave. On a scale of 'nothing will happen' to 'my account is wide open', what's the real risk, and why?
Before you work through the walkthrough, here are the four ideas you'll be using. These turn cloud storage from a convenience into something actually safe to use on a shared machine.
| Concept | Why it matters | Example |
|---|---|---|
| Cloud storage — files kept on a provider's servers and accessed through a browser, not on the computer's own hard drive | You can open your work from any computer without carrying a USB stick, and nothing is lost if the machine dies | A Work Experience placement PC crashes mid-shift; you sign in on a different computer and every file is still there |
| Sync — the cloud provider updates every signed-in device with the latest version of each file | A change you make on one machine appears on another automatically, without emailing files to yourself | You update your CV on the college lab PC; at home 10 minutes later the new version is already there |
| Version history — a record of every saved state of a file, with a button to roll back | If you or someone you shared with damages a file, you can restore a good earlier copy | You accidentally delete a paragraph from your Work Experience log; version history lets you restore yesterday's copy |
| Sharing — giving specific people access to a file or folder, with read-only or editing rights | Supervisors, Citizens Information advisors, and mentors expect shared links, not random email attachments | You share your apprenticeship application draft with a mentor for feedback using a view-only link |
When you sign in, the browser keeps you logged in until you sign out or close the session. On a shared computer that's a door into your account for the next person who sits down. Ticking 'Remember me' at login props that door open for days or weeks. The walkthrough ends with a clean sign-out for a reason.
In this walkthrough you'll open your cloud drive on a school account, verify a file is fully saved, test that the file opens from what acts like a second machine (a private / Incognito window), look at version history, share with a peer using view-only permission, and sign out the clean way. Use any existing document in your Digital_Portfolio folder as the file you test with.
| Issue | Solution |
|---|---|
| The profile shows a personal account instead of your school account | Click the profile circle and sign out, then sign back in with your school email. Don't just open a second tab — older tabs keep the wrong account alive. |
| Your file's title bar shows 'Saving...' or 'Uploading' and won't clear to 'Saved' / 'All changes saved' | Check your internet connection. If the connection is fine, give it 30 seconds. If it still won't finish, refresh the page — your latest typed changes may need to be re-entered, but nothing already saved is lost. |
| You realise you forgot to sign out on a shared computer after leaving | Go to your account settings from any device and choose 'Sign out everywhere' (or 'Sign out of all sessions'). Change your password straight afterwards. |
| The person you shared with says they can't open the file | Check the share dialog: if you set it to 'Specific people' they must use the exact email address you added. Make sure they are signed into that account, not a different one. |
| You accidentally shared as 'Editor' / 'Can edit' instead of view-only | Right-click the file, open the share dialog again, and change their permission to 'Viewer' / 'Can view'. The change takes effect immediately. |
