How to keep your Slack status active

Slack shows you as active with a solid green dot while the app is open and you've done something recently. It flips you to away — a hollow dot — after roughly 10 minutes of no activity, or immediately when your computer sleeps or locks. There's no official "always active" button, so keeping the dot green comes down to stopping those two triggers.
How Slack decides you're active
Slack's own help documentation is clear that presence is automatic. You're active when the app is open and you've recently interacted with it; you're set to away automatically after a period of inactivity, or when your device goes to sleep. Two consequences follow from that:
- It's tied to the Slack app being open and your machine being awake, not to you typing in Slack specifically. Working in another app keeps the OS active, which keeps Slack active.
- Locking or sleeping the machine ends it instantly, no matter how recently you were typing.
This is the same idle-detection model behind Teams, and the mechanics carry over directly from keeping your Teams status green.
The setting you actually control
Slack gives you one real lever here, and it's a manual one. Click your profile picture, and you can Set yourself as active or away by hand. Setting yourself active manually tells Slack to keep showing the solid dot — but this override still gives way when your computer sleeps or locks, so on its own it doesn't survive you stepping away.
There is no user setting to extend the ~10-minute idle window or to disable away entirely. Anything beyond the manual toggle means keeping the machine itself awake and active.
Keeping the machine awake and active
Because Slack follows the operating system, the reliable way to hold the green dot when you step away is to stop the machine going idle. There's an important distinction here that trips people up:
Stopping the screen from sleeping is not the same as stopping you being marked idle. Slack cares about the second one.
A browser wake lock keeps the display on, which is enough if your only problem is the screen dimming while you read. But it sends no input, so Slack's idle timer keeps running and the dot still goes hollow. To hold the status you need something generating actual activity:
- Free software. A jiggler that produces real, varied mouse movement resets the idle timer, so Slack keeps you active. The free download on our homepage does this with randomised movement — see how mouse jigglers work for the mechanics.
- Hardware. On a locked-down machine where you can't install anything, a Vaydeer S4 USB mouse jiggler plugs in as an ordinary mouse and needs no software. The honest caveat is in software vs. hardware: tightly-managed laptops can still block unknown USB devices, so try the free route first.
If it flips to away anyway
Two common reasons the dot still goes hollow while a keep-awake is running:
- You're using a browser wake lock, not real input. That keeps the screen on but not your status. This is the single most common mix-up — it's cause #2 in why your mouse jiggler isn't working.
- The Slack app fully closed or the machine slept. If the computer sleeps, no amount of mouse movement helps, because sleep stops the process. Fix the sleep settings first — stopping Windows from sleeping and keeping a Mac awake cover both platforms.
One honest note
A green dot means "available," not "working," and most managers know the difference. Presence is a weak signal, and the useful thing a jiggler does here is stop a status light flipping to away during a long call, a build, or ten minutes reading a document — not manufacture a full day of fake activity. If your workplace has a policy about simulating activity, that's worth reading first; we go through the risk in can you get fired for using a mouse jiggler.
Bottom line
- Slack goes away after ~10 minutes idle, or instantly on sleep/lock.
- Set yourself active manually for a quick fix — but it drops when the machine sleeps.
- To hold it while away, keep the machine active with real mouse input, not just a screen wake lock.
- Still flipping? You're likely using a wake lock, or the machine is sleeping.
