Account Login Details
Section titled “Account Login Details”Supported Login Methods
Section titled “Supported Login Methods”YYNote supports the following login/registration methods:
| Login Method | Description | Register New Account | Bind to Existing Account |
|---|---|---|---|
| Scan QR code to authorize | ✅ | ✅ | |
| Scan QR code to authorize | ✅ | ✅ | |
| Google account authorization | ✅ | ✅ | |
| Apple | Apple ID authorization (iOS/HarmonyOS) | ✅ | ✅ |
| Huawei | Huawei account authorization | ✅ | ✅ |
| Microsoft | Microsoft account authorization | ✅ (via Settings on each platform) | ✅ |
⚠️ Important: Each login method creates an independent account — data is not shared between them. For example, WeChat login and QQ login are two different accounts.
💡 Microsoft Account: You can bind a Microsoft account to an existing account via Settings on any platform, or use it to register a new account.
⚠️ Important: The six methods above are separate accounts — data is not interoperable. For example, WeChat login and QQ login are different accounts.
Same Login Method = Same Account
Section titled “Same Login Method = Same Account”YYNote uses a UNID (User Unique Identifier) to bind accounts. The same OAuth account on different devices will automatically bind to the same account, and data syncs seamlessly.
Example: Log in with WeChat on your phone → account is created. Log in with the same WeChat on your computer → it automatically binds to the same account on your phone, and your todo data is identical.
Note: Different OAuth methods (e.g., WeChat vs. QQ) are still different accounts — data is not shared.
Multi-Device Login
Section titled “Multi-Device Login”You can be logged in on multiple devices at the same time. Data syncs in real time after login.
Important: Different Login Methods = Different Accounts
Section titled “Important: Different Login Methods = Different Accounts”⚠️ WeChat, QQ, Google, Apple, Huawei, and Microsoft — each login method is a completely independent account. Data is not shared between them.
Recommended approach: Choose one primary login method, then bind other methods to merge them into the same account.
Binding Multiple Login Methods
Section titled “Binding Multiple Login Methods”After binding, a single account can be accessed using multiple login methods, with fully synced data.
How to bind: Settings → Account Management → Bind Other Accounts → Choose the login method to bind
Binding rules:
- The same login method cannot be bound twice (if it is already bound to another account, it cannot be bound again)
- After unbinding, that login method returns to a free state and can be used to log into or register a new account
Example:
- Log in with WeChat → Account A
- Bind QQ in Account A → After that, logging in with QQ also enters Account A, with the same data as WeChat login
Switching Accounts
Section titled “Switching Accounts”If you log in and find your data is empty, it means you logged into a different account.
How to switch: Sign out of the current account → Switch login method → Sign in again → Find your previous account
