If you are having trouble logging into Slack, make sure the account credentials you are using are accurate. Users frequently misunderstand or forget their login information for an account, especially if it remains logged in on their devices.
Check both your email address and password before checking in. If you can’t remember your Slack account’s password any longer, you can also reset it.
Method 3: Turn Off Your Device
Before beginning more complex troubleshooting procedures, we advise verifying your credentials and restarting your device. By doing this, you can make sure that the resources on your device are loaded properly.
You can restart your computer using Windows by carrying out the following actions:
To open the Start Menu, press the Windows key on your keyboard.
The Power Options tab should then be selected.

Click the Restart button to finish.
Check out the instructions below to restart macOS:
First, open your Mac’s Apple Menu.
Select the option to restart now.

Finally, in the dialogue box, click the Restart button.
Method 4: Check Your Network Connection
If you are having trouble logging into Slack, your network might be having trouble. Slack may encounter issues when attempting to validate your login information from the servers if your internet connection is unreliable. You may check this by measuring the current upload and download speeds of your network on “network speed testing sites.”
If the outcome indicates that your network is operating slowly or unstable, restart your modem or router. Reconnect the power wire after waiting five to ten seconds after unplugging it from the outlet. Run another speed test after restarting your router to verify that the issue has been resolved.
In the event that it does not, get in touch with your internet service provider and ask them to fix the problem with your internet connection.

In the event that you are still unable to log into Slack, we advise seeing a specialist. Visit the Slack Help Center and get in touch with customer support to report a problem with your account.
