One of Slack's strengths is that a single account works everywhere at once. Here is how to run Slack on your PC, Mac and phone with everything kept in sync.
Your Slack identity — your account, channels and message history — lives in the cloud, tied to your account rather than to any one device. When you sign in on a new device, Slack downloads that data, so your conversations are there instantly. Send a message from your laptop and it appears on your phone moments later, and a message you read on one device is marked read on the others.
Download and install the official Slack app on every device you want to use — Windows, Mac, Linux, iPhone or Android.
On every device, sign in to the same workspace with the same account. This is what links them to one synced experience.
Slack may ask you to verify a new device by email or another method as a security step. Approve it to finish connecting.
Your channels and recent messages download automatically. Give it a moment on first sign-in, especially for large workspaces with lots of history.
Configure notification preferences on each device, since these are stored locally — for example, full alerts on desktop and quieter ones on mobile.
Yes. Slack is designed to run on a desktop and a mobile device at the same time. Messages and channels stay in sync, so you can start a conversation on your phone and continue it on your computer without missing anything.
Your messages, channels and workspaces live in the cloud against your account. When you sign in on another device, Slack pulls that data down, so your conversations appear automatically and new messages arrive everywhere in real time.
Account-level data syncs, but some preferences are stored per device. Slack lets you set different notification rules on desktop and mobile, so you can be quieter on one device while staying reachable on another.
Download Slack and sign in with one account to sync everywhere.
