Shared Floor Computers: Facebook Session Rules for Reps

Saturday at 11:40 a.m. A customer is on the lot looking at a three-year-old truck. The assigned rep walks to the shared desk PC to pull up the Marketplace listing so he can answer a price question from a different buyer already in Messenger. Facebook is signed in as last night's closer. The inbox is someone else's. The photo picker is half-open on a unit that is not even on this rooftop. He posts anyway, because the desk manager is waving him back to the truck, and by Monday the used-car manager is trying to explain why two listings went out under the wrong identity.

Shared floor computers are normal on a dealership. One desk PC next to the printer, one tower in the tower, one kiosk in F&I that everyone "just uses for a minute." What is not normal is treating the Facebook session on that machine as communal property. Session mixing is how you get listings under the wrong name, inbox chaos, password-reset storms, and the kind of account-behavior noise that looks like a compromised login. PostToMarket is not affiliated with, endorsed by, or sponsored by Meta. This article is about the operating rules that keep a shared PC from becoming a Marketplace liability.

These Facebook session rules for reps are conservative operating standards, not published platform requirements. Check Meta's current commerce policies and Marketplace rules before you change how your store logs in. The goal is simple: one person, one session, one queue, even when the hardware is shared.

Why Shared Floor Computers Need Facebook Session Rules

A private seller's laptop has one owner. A floor PC has a rotating cast: the morning greeter, the closer who stays late, the associate covering lunch, the manager who "just needs to check one thing." Facebook cookies, saved passwords, and open tabs do not rotate with the people. They persist until someone signs out, and most people do not sign out.

What actually sits in the session

When a rep is signed into Facebook in Chrome, the browser holds more than a name in the corner of the page:

• The identity that Marketplace will treat as the seller.
• Open Composer state, draft photos, and half-filled vehicle fields.
• Messenger threads that belong to that identity.
• Saved login hints that make it easy for the next person to stay in the same account without noticing.

If the next person posts, messages, or even opens Marketplace, they are acting as the previous person. That is not a technicality. It is a live listing under the wrong seller, a reply from the wrong inbox, and a behavior pattern that looks like several people using one account from one device in a short window.

Why "just this once" is the expensive pattern

The justification is always the same: the assigned computer is occupied, the customer is waiting, the associate does not have a laptop, the closer forgot to sign out. One exception becomes the default. Within a week you have:

• Listings that cannot be found later because nobody remembers which identity posted them.
• Sold units still live because the person who posted them is off today and nobody else can manage that account cleanly.
• Password resets because two people tried to "fix" a locked session at the same time.

If you already suspect that several people are using one Facebook login on purpose, read Why Sharing One Facebook Login Across Reps Is Risky before you write any floor rules. Session mixing on a shared PC is the accidental version of the same problem.

Hardware sharing is not the same as identity sharing

You can share a desk. You cannot share a Facebook identity without creating operational debt. The rule is not "buy a laptop for every associate tomorrow." The rule is: when a person sits down at a shared floor computer, they bring their own session and they leave with it.

Facebook Session Rules Every Rep Should Follow on Shared Floor Computers

Write these on a laminated card next to the monitor. Train them in ten minutes. Enforce them the first time someone skips a step.

Rule 1: Confirm the identity before you touch Marketplace

Before you open a listing, look at the Facebook name and profile photo in the browser. If it is not you, stop. Do not post, do not reply, do not "just look." Sign out, then sign in as yourself.

A useful floor habit: say the name out loud. "I am posting as [name]." It sounds silly until it catches the closer's account still sitting on the machine.

Rule 2: One Chrome profile per person who uses the PC

Do not keep a single Chrome window that everyone inherits. Create a Chrome profile for each rep who is authorized to post from that machine. Profiles keep cookies, extensions, and Facebook sessions apart. The setup is covered in more depth in Chrome Profiles to Separate Personal and Dealer Facebook. On a shared floor computer, profiles are not a nice-to-have. They are the only practical way to keep Saturday's closer from contaminating Sunday's opener.

Each profile should contain:

• That rep's Facebook session only.
• The PostToMarket Chrome extension signed in with that rep's own email, not a shared inbox.
• Bookmarks for Inventory, Queue, and Marketplace. Nothing else required.

Rule 3: Sign out at the end of the seat, not at the end of the day

End-of-day sign-out is too late. The next person sits down in twelve minutes. The session rule is: when you stand up from a shared floor computer, you sign out of Facebook, you lock Windows, and you close the profile window. If you are walking a customer to a unit and will be back in two minutes, lock the workstation. Do not leave Marketplace open.

Rule 4: Never save Facebook passwords in a shared Chrome profile named "Default"

Password managers on a communal Default profile turn the next click into an automatic login as whoever was last. If the store uses a password manager, it belongs in the individual's profile, tied to that person's credentials, with a master lock. Saved passwords in a shared Default profile are an open key to every account that has ever been used on that PC.

Rule 5: Do not finish someone else's Composer

A half-filled Marketplace form is not a gift. It is a trap. If you sit down and see year, make, mileage, and photos already loaded, close it. Starting from a previous user's draft is how you publish the wrong price on the right photos, or the right price on the wrong VIN.

Rule 6: Post from your queue, not from whoever left a tab open

If your store uses a posting queue, the unit you post should already be on your queue. Grabbing a random inventory tab from the last user is how two people post the same vehicle. For the ownership model behind that, see One Account Per Rep or a Shared Store Account: How to Choose.

A Shared-PC Checklist for the Used-Car Desk

Use this as a start-of-seat and end-of-seat ritual. It takes under a minute once it is habit.

What managers should audit weekly

• Walk the shared PCs and see whether Default still has a live Facebook session.
• Ask two associates to show you which Chrome profile they use. If they cannot find it, they are using someone else's.
• Check whether listings from the last seven days map to the people who were on the floor. If a unit posted at 9:15 p.m. under a rep who left at 6:00 p.m., you have a session problem.
• Confirm that seasonal and temp staff received the same session briefing as full-time reps.

Edge cases on a real floor

The only PC is in the closer's office. Put Chrome profiles on it anyway. The closer does not own the Facebook identities of everyone who borrows the chair.

A customer is waiting and the assigned profile will not load. Do not switch into a coworker's session to "just get it up." Use your phone's mobile dashboard to confirm price and status, then return to post when the machine is right. Speed that creates a wrong-identity listing is not speed.

IT images every PC from one clone. Cloned images often include a Default profile with leftover extensions and cookies. After imaging, create the named profiles and sign into Facebook from a clean state. Do not copy a profile folder from another user.

Someone used Incognito "to be safe." Incognito avoids saving the session, which sounds responsible and then produces a login prompt every time, plus a higher chance the next person uses the normal window that still has yesterday's cookies. Use named profiles, not Incognito, for production posting.

How to Roll Out Session Rules Without Slowing the Floor

Rules that add three minutes of friction will be ignored. Design the environment so the correct path is the easy path.

Name the profiles after people, not jobs

"Sales 1" and "Internet" become communal again within a week. Use the rep's first name and last initial. When that person leaves, delete the profile. Do not recycle it.

Put the extension only in those profiles

If the PostToMarket extension lives in Default, people will keep using Default. Install it in each named profile and leave Default without posting tools.

Give associates a queue before you give them the shared PC

An associate who sits down without a queue will hunt through inventory and inherit whatever tab is open. Managers should assign vehicles to associate queues in the morning so the shared-PC session is used to execute work, not to browse the lot.

Train the lock-screen reflex

Windows + L is faster than an argument about who left Facebook open. Make it part of the same muscle memory as hanging up the desk phone. If the PC auto-locks after a long idle period, shorten that idle time on shared machines.

Write the exception path

There will be days when a laptop dies and three people need the same tower. The exception path is: switch Chrome profiles, confirm identity, post from your queue, sign out. The exception path is never: stay in the previous session.

How PostToMarket Automates This

Shared floor computers create Facebook session chaos when several people inherit one browser identity and then try to post inventory by hand. PostToMarket does not replace the need to sign out, but it removes the reasons reps steal a session: hunting for which unit to post, retyping copy, and racing to "catch up" on a communal PC.

Queues that belong to a person, not a desk

• Personal posting queues and per-rep queues so the work is waiting under the right name before anyone sits down.
• Managers assign vehicles to associate queues; sales reps self-queue from shared inventory. The associate does not need to browse someone else's open tabs.
• Team queue view so a manager can see a stuck claim and release it without logging into that rep's Facebook session.

Posting that does not require a frantic shared-PC burst

• The Chrome extension posts one vehicle at a time with human-like delays, so there is no reason to occupy the desk PC for a twenty-unit dump.
• Server-enforced daily post limits and delays keep a rep from treating a free terminal as a license to blast the backlog.
• Sign in to the extension with email (no API keys), in that rep's Chrome profile, so the tool identity matches the person in the chair.

Status that survives a shift change

• Inventory statuses (draft, posting, posted, sold, failed) are visible on the dashboard, not trapped in a Facebook tab someone left open.
• Mark as sold and archive from inventory or the queue so the next shift does not keep advertising a unit that moved.
• The mobile dashboard can be installed on a phone's home screen so a rep can reorder the queue between customers instead of monopolizing the shared PC.

The remaining discipline is human: confirm the Facebook name, use your profile, sign out when you stand up.

Make the Shared PC Boring Again

A shared floor computer should be as dull as a shared stapler. It should not be the place where identities mix, listings go out under the closer's name, and Monday's reconcilation is a scavenger hunt. Facebook session rules for reps are how you keep hardware sharing from becoming account sharing.

If your team still posts by hunting through whoever left Facebook open, you are spending floor-plan interest on avoidable rework. PostToMarket puts unlimited vehicles in inventory, gives each person a queue, and lets the Chrome extension post one unit at a time from a signed-in profile that belongs to that rep. Starter is $59 per month for a solo seller who needs one login. Dealership is $299 per month when you need up to 13 logins across admin, managers, reps, and associates.
