To leave a Slack workspace, access the Slack account page, enter your password, and deactivate the workspace.
If your company uses Slack, you don't need to unsubscribe yourself when you leave; your administrator will handle the process.
Workspace settings, etc., require you to log in when accessing the Slack web page. If you use Google/Apple login, you may still need to set a Slack password.
You can create multiple Slack workspaces or be invited to join multiple workspaces.
Some companies use Slack as a community platform, which is why you might be part of multiple workspaces. However, you might want to leave a community because you don't want to receive notifications or because it's no longer relevant to you.
Let me explain how to leave a Slack workspace directly.
If your company uses Slack, your administrator will remove you when you leave the company, so you don't need to worry about it.
Access the link above. If you are not logged in, Slack will prompt you to open a web page window.
For example, you can click the [Workspace Settings] button.
When you access the link above, you might be asked to enter your password. Even if you used Google or Apple login, you might be asked for your password. Click "Do you need to create or reset your Slack password?" below, and Slack will send you a password setup link via email.
After checking your email and setting your password, you can deactivate your account.
