Using Two Slack Workspaces on iPhone or iPad

If you belong to more than one Slack workspace—say, for work and a side project—you can juggle them all from a single iPhone or iPad app. This guide shows you how to add, switch between, and manage multiple workspaces, so you never miss a message. You’ll need the Slack app installed and your login credentials for each workspace ready.

What You’ll Need

iPhone or iPad with iOS 15 or later (for the latest Slack app features)
Slack app installed from the App Store
Login credentials (email/password or SSO) for each workspace you want to add
If your workspace uses Single Sign-On (SSO), have your company’s Slack URL or login page handy

Step-by-Step

Open the Slack app on your iPhone or iPad. If you’re not logged in, you’ll see a welcome screen. If you’re already logged in to one workspace, you’ll land on its default channel.
Access the workspace switcher. Tap your profile picture (bottom-right corner on iPhone, top-left on iPad) to open the sidebar. Then tap the workspace name at the very top of the sidebar. This opens the workspace switcher screen.
Add a new workspace. On the workspace switcher screen, tap the “+” icon (usually in the top-right corner) or the “Add workspace” button. You’ll be prompted to either “Create a new workspace” or “Sign in to an existing workspace.” Choose the latter.
Enter your workspace URL. Type the workspace’s Slack URL (e.g., yourcompany.slack.com) and tap Continue. If you don’t know the URL, tap “Find my workspace” and enter your work email to get a list of workspaces associated with it.
Sign in. Enter your email and password, or use the SSO option if your workspace uses it. Follow any additional verification steps (like a magic link or two-factor authentication).
Wait for the workspace to load. Slack will take a few seconds to sync channels and messages. Once done, you’ll see the new workspace’s channels in your sidebar.
Switch between workspaces. To jump between workspaces, tap your profile picture again, then tap the workspace name at the top. You’ll see a list of all your workspaces. Tap the one you want to open. Alternatively, use the three-finger swipe gesture (swipe left or right with three fingers) on the main screen to quickly cycle through your workspaces.
Set a default workspace (optional). If you want the app to always open to a specific workspace, go to Settings (gear icon) > Advanced > Default workspace and select your preferred one. This is handy if you use one workspace more than others.

Common Mistakes

Using the wrong sign-in method: If your workspace uses SSO (like Google or Okta), don’t try to sign in with an email/password. Use the SSO button, or you’ll get an error.
Forgetting to switch before sending: It’s easy to send a message to the wrong workspace. Always check the workspace name at the top of the screen before hitting send.
Not updating the app: Older versions of Slack may not support multiple workspaces smoothly. Keep the app updated to avoid glitches.
Confusing logout with switching: Logging out removes the workspace from your device. Use the workspace switcher to switch, not logout, unless you want to remove it.

Tips

Use the three-finger swipe to quickly flip through workspaces without opening the switcher.
Customize notifications per workspace: Go to Settings > Notifications and select a workspace to set different notification preferences for each.
Organize with folders (iPad only): On iPad, you can create folders in the workspace switcher to group workspaces (e.g., “Work” and “Personal”). Tap Edit, then drag workspaces into a folder.
Use the search feature: The global search (magnifying glass icon) can search across all your workspaces, not just the current one.
Keep your workspaces signed in: Slack remembers your login, so you don’t need to re-enter credentials every time you switch.

Troubleshooting

Can’t find the workspace switcher: Make sure you’re on the main Slack screen (not in a direct message or search). Tap your profile picture, then the workspace name. If it’s not there, try restarting the app.
Workspace not loading: Check your internet connection. If it’s fine, force-close the Slack app (swipe up from the bottom and swipe the app away) and reopen it.
Sign-in errors: Double-check your workspace URL and credentials. If you’re using SSO, try opening the SSO link in a browser first to ensure it works.
Workspace disappears: If a workspace vanishes from your switcher, you may have been logged out (e.g., due to a password change). Re-add it by following the steps above.
Notifications from wrong workspace: If you’re getting notifications from a workspace you’re not currently viewing, that’s normal—Slack notifies you for all workspaces. Adjust notification settings per workspace if it’s too noisy.

Frequently Asked Questions

Can I use Slack for free with multiple workspaces?

Yes, the free plan allows you to join and switch between an unlimited number of workspaces. Each workspace has its own limits, but you can be a member of as many as you like.

How do I remove a workspace from my iPhone?

Open the workspace switcher, tap the “…” next to the workspace you want to remove, then select “Log out.” This removes it from your device, but you can re-add it later.

Will I get notifications from all workspaces at once?

Yes, by default you’ll receive notifications from all your workspaces. You can customize this by going to Settings > Notifications and selecting a specific workspace to adjust its alert settings.

Can I use the same email for two different workspaces?

Absolutely. Your email is just your login identifier. You can use the same email to join multiple workspaces, even if they’re unrelated.

Is there a limit to how many workspaces I can add?

No, Slack doesn’t impose a limit on the number of workspaces you can join. However, performance may degrade if you have an excessive number (e.g., dozens) due to storage and sync demands.

Why can’t I see a workspace that I know I belong to?

If you’re not seeing a workspace in the switcher, you might have been removed or logged out. Try adding it again using the workspace URL. If that fails, contact the workspace admin to confirm your membership.
