You can choose a display name to show when your coworkers mention you in Slack. If you don't fill in the display name field in your Slack profile, you'll see your full name when people mention you. 

Full name You must include a full name in your profile. Unless you've updated your profile, we use the full name you gave us when you created your account.

 

Display name Display names are optional and can contain spaces, non-English characters, and capitalization.

Set your display name

Note: If single sign-on is enabled for your workspace, your ability to edit your personal information, including display names and email addresses, may be restricted.

Reserved names

There are several words that we reserve to avoid confusion in Slack, and can't be used in full names or display names:
