Create your account
Superheat CN has no passwords. You prove who you are with a one-time six-digit code: by SMS to your phone by default, or to your email. The same flow both creates an account and signs you back in — there is no separate "register" step. If the number or address has never been seen before, an account is created; if it has, you're signed in.
Open console.superheat.cloud. The sign-in card has a Phone / Email switch at the top (手机号 / 邮箱 in the 简体中文 console), with Phone selected.
Sign in with your phone
- Enter your mainland-China mobile number under Mobile number. The country code is fixed at +86. The Continue with SMS button stays greyed out until the number is a valid mainland mobile number.
- Select Continue with SMS.
- On the Check your phone screen, type the 6-digit code from the text message, then select Verify & continue. Pasting works too — one paste fills all six boxes.
| Item | Rule |
|---|---|
| Number | Mainland-China mobile numbers only (+86) |
| Code | 6 digits, valid for 300 seconds (5 minutes) |
| Resend | Available 60 seconds after a code is sent; until then the button counts down, e.g. "Resend in 45s" |
Numbers from Hong Kong, China; Macao, China; and Taiwan, China cannot receive the code yet, and the sign-in card says "mainland China numbers only". Until they are switched on, sign in with your email.
Sign in with your email
- Choose Email on the sign-in card, enter your address, then select Continue with email.
- Look for a message from noreply@superheat.cloud with the subject "您的 Superheat 登录验证码" (your Superheat sign-in code). It carries only the 6-digit code — no sign-in link.
- On the Check your email screen, type the code, then select Verify & continue.
An email code is valid for 600 seconds (10 minutes), as the email itself says, and you can again request a new one only after 60 seconds. If nothing arrives within a few minutes, check your spam folder.
When a code doesn't work
| Message | What it means | What to do |
|---|---|---|
| Enter a valid mobile number | The sign-in service rejected the number (an incomplete number keeps the button greyed out, so this is rare) | Check the number and try again |
| Please wait before requesting another code | Codes were requested too often, or the platform reached its limit for this hour — 60 text messages or 600 emails | Wait a moment, then select Resend code; if it keeps appearing, sign in with your email |
| That code is wrong or has expired | The code was mistyped, or its validity ran out | Select Resend code and enter the new one |
| The SMS could not be sent. Try again in a minute. | The text message did not go out | Try again in a minute, or sign in with your email |
A phone number and an email are two accounts
A mobile number and an email address each identify their own account. Signing in by email after creating an account with your phone does not reach the same account — it creates (or opens) another one, and the console has no way to link the two. Pick one method and keep using it.
If you are going to join a colleague's organization, use email. Invitations are addressed to an email address, and an account that signs in by phone only has no email, so it cannot accept one.
Superheat CN offers no Google, GitHub or other third-party sign-in.
Your personal organization
Every resource in Superheat — instances, credits, templates, API keys — belongs to an organization, never directly to a user.
The first time you sign in, a personal organization is created for you automatically. You are its admin. Nothing is required from you; it exists so you can deploy immediately.
Later you might also be invited to a colleague's organization. You then belong to two, and switch between them in the console. Credits, instances and API keys do not cross that boundary — an organization's balance pays only for that organization's work.
See Teams for how membership and roles work.
Securing the account
Once you're in, Settings → Two-factor authentication adds a second factor: the usual six-digit rotating code from an authenticator app (TOTP). It is the only second factor on Superheat CN, and it is worth enabling on any account that can spend money. See Two-factor authentication.
