Can you download SSO without having to create a new ACC and where can you confirm your email address after starting the game?

My colleague has downloaded SSO and started to play, when she tried to use the chat, the message came that she still has to confirm her email address. She did not do that when creating the account and did not receive any mail from SSO. Where can you confirm this afterwards?
I have a second question and that is, can I download SSO without creating a new account? My colleague wants to download SSO on another laptop and continue playing with her existing ACC, is that possible?

Yes, I also have a new laptop and logged into the website and then clicked download.

If she really didn't get the email (and it's not in the spam folder), she must contact support via the Star Stable page.

That's exactly why you have an account. To be able to log into different devices.
