Start with the question the device list can actually answer
A device entry tells you that some device has been authorized to access your Steam account. It does not, by itself, tell you that someone broke in, that a session was hijacked, or that anything was downloaded. Treat each unfamiliar entry as a question to resolve, not as a verdict.
The useful question after a shared computer is narrower: which devices should still have access, and which should not? Everything below is organized around answering that.
A review checklist for the account owner
Work through these in order, and stop to note what you find before changing anything.
- Confirm you are signed in to the account you mean to review. If you are unsure, sign in again from a device you control.
- Open Steam’s Authorized Devices settings and read the full list of devices with access.
- For each entry, ask: do I recognize this device, and did I authorize it? A recognizable home PC is different from a machine you cannot place.
- Deauthorize anything you do not trust. Steam recommends reviewing Authorized Devices and using Sign out everywhere when something looks wrong, and deauthorizing untrusted devices after a forgotten cafe logout.

- After deauthorizing, sign in again from your own device to confirm you still have access.
- If you changed your password as part of this review, keep the new one in a place you control, not in a note on the shared machine.
Decision table: what an unfamiliar entry might mean
| What you see | What it can mean | What it cannot prove | Sensible next step |
|---|---|---|---|
| A device you recognize from your own home | Normal authorized access | Nothing about other devices | Leave it unless you have another reason to remove it |
| A device you used once at a cafe, library or workplace | A session you started and forgot to end | That someone else used it | Deauthorize it and sign out everywhere |
| A device you cannot place at all | An old device, a family member, or something you did not authorize | That an attack occurred | Deauthorize it, then review your account access |
| A location entry that looks unfamiliar | A trip, a VPN, or a device you no longer own | That your account was compromised | Check it against your own history before acting |
| Someone contacts you claiming to be Steam support | A possible impersonation attempt | That the message is genuine | Do not follow links or move to another chat app; reach support independently |
A location or device entry is not evidence of an attack on its own. The table is a way to sort what you know from what you are assuming.
Reaching support on your own terms
If something still looks wrong after you have reviewed and deauthorized devices, contact Steam support through a route you opened yourself, not through a link or invitation that arrived in a message.
Steam warns that support does not contact users through the Friends network or ask them to move to Discord or another chat service to resolve a false report.

That warning matters after a shared-computer session because a stranger who used the same machine may know your username. A message that arrives soon afterward and claims to be resolving a report is exactly the kind of contact to treat with suspicion.
What this review does not do
Be clear about the limits, because overstating them leads to worse decisions.
- Deauthorizing a device or signing out everywhere ends access from that session. It does not delete game files already downloaded to a computer.
- Removing a device from the list is not the same as closing the account, and it does not by itself prove that stored data has been deleted.
- A device list is not a complete record of everything that has ever happened on the account.
- You cannot tell from the list alone whether a device was used by you, by someone you know, or by a stranger.
If you are worried about more than device access, handle account security and account closure as separate tasks, and keep a recovery method you control until any closure is complete.
Where a username search fits, and where it does not
A public username search, such as the one TraceSeek offers across 3,000+ platforms, can show where a known public username appears. That can be useful context if a stranger who used the shared computer knows your handle and you want to see what is publicly visible under it.
It cannot sign in to your Steam account, change account settings, or verify who a person really is. A matching username or profile is a lead, not proof of ownership. Do not treat a public match as evidence that someone accessed your account, and do not expect a search to remove anything.
A short recap
Review Authorized Devices, deauthorize what you do not trust, use Sign out everywhere when something looks wrong, and reach support through a route you opened yourself. Treat every unfamiliar entry as a question, not a conclusion.
