How to Manage Multiple Accounts on the Binance App: Switching Between Master and Sub-accounts

Using a main account for trading, a secondary account for grid trading, and a third for experimental strategies is a common practice. First, ensure you are logged in via the Binance Official Website and the Binance Official App (see the iOS Installation Tutorial for iPhone). This article explains three multi-account solutions.

Comparison of Three Solutions

Solution	Best For	Difficulty
In-App Account Switching	Multiple independent accounts	Low
Sub-accounts	Isolating positions under one master account	Medium
Device Isolation	Completely independent operations	High

Solution 1: In-App Account Switching

The Binance App supports maintaining login states for multiple accounts simultaneously, allowing for one-tap switching.

Adding an Account

1. Tap the Profile icon in the app.
2. Tap the dropdown arrow next to your account name at the top.
3. Select "Add Account."
4. Enter the email/password and 2FA for the second account.
5. Done.

Switching

Tap Profile → Account Dropdown → Select the target account. The switch happens in seconds.

Limitations

• You can keep up to 5 accounts logged in at once.
• Switching usually requires Face ID / Biometric verification.
• Push notifications only display for the currently active account (others will appear in the notification center but won't pop up).

Solution 2: Sub-accounts

Binance provides a "Sub-account" system where several sub-accounts can be created under a single master account.

Use Cases

• Isolating funds for different strategies (e.g., high-frequency vs. long-term holding).
• Granting specific trading permissions to team members.
• Isolating Futures risk (a liquidation in one sub-account does not affect others).

How to Enable

Log in to the master account → Profile → Sub-account → Create.

Each sub-account features:

• A unique email.
• Shared KYC from the master account (no need for re-verification).
• Independent API keys.
• One-tap fund transfers from the master account.

Requirements

Certain features, such as multiple sub-accounts or institutional sub-accounts, may require a specific VIP level for the master account.

Difference Between Multiple Accounts and Sub-accounts

Dimension	Multiple Independent Accounts	Sub-accounts
Independent KYC	Yes	No
Asset Independence	Completely independent	Managed by the master account
Visibility	Hidden from each other	Master can see all
Best For	Different personal roles	One person/team with multiple strategies

Solution 3: Device Isolation

If you want complete separation between accounts, the most secure method is using different devices.

• Main Trading Account: Primary iPhone.
• Long-term Holdings: iPad.
• Experimental Account: An older Android phone.

Physical isolation ensures that if one device is compromised, the others remain safe. The downside is the need for multiple devices and the inconvenience of switching between them.

Common Pitfalls with Multiple Accounts

1. Notification Confusion

Notifications from inactive accounts may appear in the notification bar without a banner, leading to missed alerts. Solution:

• Enable email/SMS notifications as a backup for each account.
• Consolidate critical operations into one account.
• Use a dedicated device for high-net-worth accounts.

2. Operational Errors

Placing an order on the wrong account after switching is a frequent mistake. Solution:

• The top-right corner of the home screen always shows the current account name.
• Double-check the account before placing large orders.
• Use distinct profile pictures for different accounts.

3. Cross-account Transfers

Transfers between a master and its sub-accounts are handled directly within the app. However, transfers between different master accounts cannot be done directly; you must use "Internal Transfer" (Pay or internal address).

4. Risk Control

Frequent switching between accounts or large operations from the same IP address within a short period may trigger risk alerts. Solution:

• Avoid excessive switching frequency.
• Space out large operations.
• Bind unique emails and phone numbers to important accounts.

Advanced Strategies for Sub-accounts

Isolating Futures Risk

Keep spot assets in the master account and use a sub-account for Futures. If the sub-account faces liquidation, the master account assets remain untouched.

Parallel Strategies

Use Sub-account A for Grid trading, Sub-account B for Futures, and Sub-account C for API-driven trading.

Team Permission Hierarchy

• Sub-account 1: Trader (Read-only + Order placement).
• Sub-account 2: Risk Control (Read-only).
• Sub-account 3: Finance (Transfer permissions). Each sub-account has its own API with strictly controlled permissions.

FAQ

Q: Does switching accounts in the app require Face ID again? A: By default, yes. You can disable Face ID requirements for specific accounts in the settings.

Q: Can I run Futures on two accounts at once? A: Yes. Each account has its own margin and liquidation price.

Q: Can sub-accounts use APIs? A: Yes. Quantitative strategies often use sub-accounts to isolate risks via API.

Q: Does forgetting the password for one account affect the others? A: No. Each account has its own independent credentials.

Q: Can a sub-account be converted into an independent account? A: No. A sub-account is permanently tied to the master account. If you need an independent account, you must register a new one.
