If you’re stuck staring at a QR code or confused by the Slack desktop app, you’re not alone.
Mastering login is key to unlocking powerful Slack use cases—from team collaboration to streamlined workflows.
Let’s walk through the steps so you can open Slack, rejoin your channels, and focus on what really matters: getting work done.
How to Do Slack Login and Troubleshoot Common Issues
What Is Slack and Why Do People Use It?
Slack is the digital office for remote teams, freelancers, and companies managing work across time zones.
Think of it as the place where your project management, daily check-ins, direct messages, and quick file drops all live together.
People often prefer to use Slack because it helps reduce chaos. Instead of endless emails, Slack offers organized channels, searchable chats, and tool integrations to help teams work together and collaborate better.
It works across desktop and mobile devices, and switching between Slack workspaces is just a few clicks away. Whether you’re collaborating across departments or working on solo projects, Slack keeps everything connected in real time.
How to Log in to Slack
Logging in to Slack is simple once you know which method to use.
Whether you’re using a mobile device, a browser, or the Slack desktop app, the process is similar, but the details matter. Here’s how to do it right:
Option 1: Log in via browser
- Go to slack.com/signin
- Enter your workspace name or email address
- Choose the right Slack workspace from the list (if there are multiple)
- Enter your password or use single sign-on (SSO) if enabled
- Click Sign in
- If prompted, enter the confirmation code sent to your email (check your spam folder if you don’t see it)
Option 2: Log in via Slack Desktop App
To do this, open Slack on your desktop and:
- Click Sign in to Slack
- You’ll be redirected to your browser to complete the sign-in
- Enter your email address, then follow the same steps as above
- Once done, your Slack workspace will open in the app
- Use the workspace icon in the top left corner to switch between accounts
💡Bonus Tip: Master the art of async communication. Once you’re logged in, not every conversation needs an instant reply. Learn how to communicate better across time zones and avoid burnout with this guide on asynchronous work.
Option 3: Log in via Slack Mobile App
Download and open the Slack app on your mobile device:
- Tap Sign in
- Enter your email address and tap Continue
- Choose your Slack workspace, then enter your password or complete two-factor authentication
- You can also scan the QR code displayed on your computer screen with your mobile device’s camera for quick access
- Tap Add workspace if you’re logging into a new workspace
❗️Attention: Switching between chat, work, and AI tools is literally killing your productivity. According to our data, 61% of knowledge workers say they spend more time managing work than actually doing it.
The average employee toggles between apps 1,200 times a day—losing hours each week to context switching and fragmented workflow. What if one tool can do it all? can!
What If You Forgot Your Workspace?
Can’t remember your Slack workspace name or which email you used?
It happens. Slack makes it easy to find your way back in. Here’s how to recover access:
Step-by-step: Recover your Slack workspace
- Go to slack.com/signin/find
- Enter your email address (the one you think you used for Slack)
- Click Continue
- Check your inbox for a list of Slack workspaces linked to that email
- Click the link to any workspace you recognize
- You’ll be directed to sign in or sent a confirmation code
💡Bonus tip: If you don’t get the email, check your spam folder or try a different address. If you’re still stuck, use Slack’s support or ask a teammate to check your Slack account email under their workspace settings.
Common Slack Login Issues and How to Fix Them
Slack may be a go-to team communication app, but it’s not bulletproof.
Login problems can pop up out of nowhere—killing your workflow, breaking focus, and keeping you locked out of your Slack workspace when it matters most.
Here’s a breakdown of five common Slack login issues that Slack users face and how to fix each one fast:
1. You’re not receiving the confirmation code
You’re entering your email, but Slack’s not sending that magic code to your inbox. Without it, you’re stuck. It could be sitting in your spam folder, or maybe you used a different address than you thought. This delay can derail your access just when you need it.
How to fix it:
Start by double-checking that you entered the correct email address associated with your Slack account. If you still don’t get the email, check your spam folder—that’s where most confirmation emails end up hiding.
If you’re using single sign-on, make sure you’re signed into the correct provider (Google, Apple ID, etc.). Still no email? Try clicking “Resend code” or switching to another browser or device to complete the process.
📮 Insight: About 41% of professionals prefer instant messaging for team communication.
Although it offers quick and efficient exchanges, messages are often spread across multiple channels, threads, or direct messages, making it harder to retrieve information later. With an integrated solution like Chat, your chat threads are mapped to specific projects and tasks, keeping your conversations in context and readily available.

2. Slack says your email isn’t registered
You’re sure you have an account, but Slack disagrees.
This usually happens when you’ve got multiple workspaces or use different logins (personal vs. work). It leaves you guessing which email was used during sign-up or invite.
How to fix it:
You may be entering the wrong login email, especially if you manage multiple workspaces or have signed in with a personal account by mistake.
Try going to slack.com/signin/find and entering all possible addresses. Slack will send you a list of workspaces linked to each one.
If you’re still stuck, ask a teammate to check your workspace icon and view your Slack profile to confirm the email used.
3. QR code won’t scan on a mobile device
Slack shows a QR code for quick sign-in, but your mobile device’s camera just won’t read it. It could be a permissions issue, poor lighting, or just a finicky app. It’s annoying when a shortcut becomes a roadblock.
How to fix it:
Open the Slack mobile app and make sure the camera has permission to access your mobile device’s camera. Try adjusting the lighting and keep the QR code steady on your screen.
Clean the lens if needed—sounds dumb, but it works. If it still doesn’t scan, you can always enter your email address manually and sign in that way instead.
4. Stuck on the loading screen in the Slack desktop app
The Slack desktop app occasionally gets caught in a loop during startup, especially after updates or network hiccups. You’re left staring at a loading screen instead of your conversations.
How to fix it:
Close and reopen Slack. If that doesn’t work, clear the app cache:
Mac: Cmd + Shift + Option + Y
Windows: Ctrl + Shift + Y
After clearing, try signing in again.
If you’re still stuck in the same place, delete and reinstall the Slack desktop app, or switch to the browser version temporarily to access your communication channels and files.
5. Can’t switch between workspaces
You’ve got access to several workspaces, but Slack acts like they don’t exist. Switching between them should be simple, but when accounts aren’t linked or visible, you’re forced to log out just to get into another Slack workspace.
How to fix it:
On the Slack app, click your workspace icon in the top left corner, which’ll open the sidebar. Then tap Add workspace or Switch workspaces. If you don’t see your other workspaces listed, sign out and then sign back in using the correct credentials.
Ensure that all workspaces are associated with the same email address or identity provider. If you’re using Enterprise Grid, ask your admin to confirm workspace visibility.
💡Bonus Tip: Having a Slack workspace is step one. However, to maintain efficient communication, you need structure. Use this communication plan template to build a system your team will actually follow.
