Sign in to YiTaiCOS

Before you start

Have your account identifier and password ready. Email is optional for username accounts.

Steps

Open the YiTaiCOS sign-in page. Enter your email address or global username and password in the same form, then select Sign in.
For email sign-in without a password, enter your email and select Send sign-in link. You can also use an existing passkey.
If your account has one organization, it opens directly. If it has more than one, choose the organization you want to enter. Your previous organization is not selected automatically.
Replace a temporary password when prompted. After entering an organization, use the organization control to switch to another organization you can access.

Android and iOS app

In app versions with central browser sign-in, select Continue to sign in on the existing app entry. The system browser opens the YiTaiCOS sign-in page in its mobile layout. Use your existing account, passkey or recovery options; no second account is needed. After sign-in and any required organization or profile step, you return to the app. The app checks your current organization access before opening the workspace. Cancelling returns to the sign-in entry without granting workspace access.

If organization access is missing, ask your administrator to restore it. If the browser does not return to the app, return to the app and retry sign-in. Never copy browser codes, tokens or sign-in links into a support message.

Expected result

You enter the organization you selected, with the permissions assigned there. An expired selection or changed access requires signing in again.

Switch pages

After your workspace receives the navigation update, choosing a page in the navigation menu immediately shows that page's existing loading view while its data arrives. On a phone, the menu closes after selection. You can choose another destination while waiting; the latest selection takes priority. Selecting the page you are still on cancels the pending loading view and restores that page. A loading view does not confirm that data has arrived or changes have been saved.

Navigate on a phone

After the matching workspace update is released, the mobile header shows your workspace and current page, with Search and Profile beside the navigation button. Long workspace names are shortened to fit.

Select Search to open workspace search. The current page tag, such as Products, is selected initially. Enter a name or identifier and choose a result. Close or Escape returns to the page.
Open the navigation menu for YiDuo messages, notifications and the cart. Available shortcuts depend on your workspace permissions. Choose a page to close the menu and continue there.
Desktop keeps its existing search field and header shortcuts.

If something goes wrong

Find your username in Account security or ask an administrator to check Personnel login details. Existing accounts keep one username across organizations. During migration, an older explicitly entered workspace/username login remains supported.
Without an email address, email links and email recovery are unavailable. An administrator can reset only an email-less account created and still exclusively managed by that organization. Shared and external accounts manage their own credentials; contact support if recovery is unavailable.
Keep passwords and sign-in links private. Do not paste them into a support message.
