Can I have multiple accounts/profiles in SPT?
SPT supports an unlimited number of profiles.
From the Launcher, logout of any profile by clicking "logout" in the bottom right of the window.
You should see your profile(s) in a list on the left.
Enter a username into the login box that does not currently exist, will prompt you to choose a new account type for the new profile.
if you with the swap profiles, click "logout" to see a list of available profiles again.
