Sign-in and authorization
Claude Desktop sign-in in China: email codes and app authorization
Search results often mix official Claude accounts with ClaudeU accounts. ClaudeU uses its own email-code and Desktop authorization flow: the browser confirms the account and the app receives the authorization result.
Confirm that this is a ClaudeU account
ClaudeU email sign-in connects balance, orders, usage, and Desktop authorization. It is not a purchase or custody flow for an official Claude account. Confirm the visible email before payment or authorization.
Use the Desktop-to-browser sequence
Start sign-in from Desktop, enter the email code in the opened browser, confirm the account, and return to the original app after the authorization page completes.
Recover a missing email code
Check the email spelling, spam, quarantine, and organization mail rules. Wait before requesting again and never send a code to support or another person.
Recover on a new device or expired session
Start a fresh browser handoff from the new Desktop session. If the operating system does not return focus to the app, switch back manually or start the flow again.
Frequently asked questions
Does ClaudeU require a password?
ClaudeU currently signs in with an email verification code rather than a long-lived password.
Why is Desktop not signed in after the web succeeds?
The web confirms authorization but cannot guarantee the operating system returned the result to the app. Return to Desktop or start a fresh handoff.
Will support ask for my email code?
No. Never send an email verification code through support, email, screenshots, or chat.
