How to Log In and Secure Your Stella Sora Account

Your Stella Sora account is a Yostar account bound to an email. You log in with that email, and the game checks it with a code sent to the email box when it needs to. This guide covers the right app for your server, the login itself, and the few steps that make the account yours.

What you receive

• The email address the account is bound to.
• The login details of that email box, so that you can read the codes the game sends.
• The server of your order: Global, Japan, Korea or Taiwan, as chosen on the Stella Sora starter account page.

Install the right version

Stella Sora is published by Yostar, and the Global, Japan, Korea and Taiwan servers each have their own version of the app. Install the one that matches your order: the Global app (in English, on Android, iOS and PC) cannot open a Japan, Korea or Taiwan account, and the reverse is also true. The Japan, Korea and Taiwan versions show their menus in Japanese, Korean and traditional Chinese.

Log in step by step

1. Open the game. On the title screen, do not start as a guest (the rocket icon, or "Guest Account" on mobile): a guest start creates a new, empty account.
2. Choose to log in with your email (Yostar account) and enter the email address you received.
3. When the game asks for a verification code, it sends it to that email. Log in to the email box with the details you received, copy the code and enter it in the game.
4. Check the account: the Stellanite Dust, tickets and characters listed in your order should be there.

Secure the account right away

1. Change the password of the email box. It is the key to the account: the login codes arrive there, so whoever controls the email controls the account.
2. Check the User Center. From the main screen, tap the three lines (menu), then "Settings", and "Go" next to "User Center". It shows which email the account is bound to.
3. Keep the email box. If the User Center lets you change the bound email, you can move the account to your own address; if not, keep the delivered email box with its new password.

Common problems

• The account is empty or the tutorial starts: you started as a guest, or used Google or Apple instead of the email. Go back to the title screen and log in with the email.
• No code arrives: check the spam folder of the email box, wait a minute, then ask for a new code.
• The right email opens the wrong account: you are probably on the wrong version of the app (for example the Global app for a Japan account). Install the version of your server.
• Another problem in the game: the in-game support is under "User Center", then "Contact CS".

What our after-sales service covers

If the account does not match its description, or the login details do not work, email us within 48 hours of delivery: we send a replacement or refund your order. Tell us your server and the app version you installed. Details in our FAQ and on how it works.

FAQ

Can I play on PC and on my phone?

The Global version runs on Android, iOS and PC, and you log in with the same email on each.

Can I move a Japan account to the Global server?

No: each server is a separate version of the game, and accounts stay on their own server.

Why is the email box so important?

The game sends its verification codes there, so the email box must stay in your hands.
