某些用來登錄您IB賬戶的安全設備在申請或激活時需創建一個數字或字母與數字組合的PIN碼。該PIN碼可提供額外的一層保護，有效防止意外拿到您的設備但又未被授權的個體操作設備。因此，選擇一個您容易記住且別人難以猜到的密碼尤為重要。以下列出了一系列您創建PIN碼時應考慮的指導原則或最佳方案：

• 請勿使用您個人的生日
• 請勿使用您孩子或者任何直系親屬的生日
• 請勿使用您個人或者辦公地址信息，如街道名稱、門牌號碼、郵政編碼
• 請勿使用您身份證件信息（如社保號或者身份證號碼）
• 請勿使用電話號碼
• 對於PIN碼的非數字部分，避免使用您或您的家庭成員或親屬的姓名首字母，或您所在城市的名稱或球隊的名稱
• 避免使用您本人、您的家庭成員或親屬的姓和/或名
• 我們建議在PIN碼中包含大小寫字母和數字
• 要滿足以上要求搆造一個方便記憶的PIN碼，您可以想一個句子，然后將該句子的首字母組合起來。

What is M2-FS?

M2-FS allows any client to maintain more than one active security device at the same time. No more do you have to pick and choose whether you prefer to use a physical security device or the IB Key app as either can be used interchangeably.

Back to top 

Activation

For any clients with an active security device, any further device activation will result in both devices remaining active.

I currently use the Security Code Card / Digital Security Card+: Clients who currently use a physical security device, simply need to download and activate the IB Key app. Refer to the directions for Android and iOS for details.

I currently use the IB Key app: Clients who currently use the IB Key app and qualify for the Digital Security Card+, can proceed to login to Account Management and request said device¹ by navigating to Manage Account -> Security -> Secure Login System -> Security Device.

1: The DSC+ is available to accounts with a balance greater than USD 500,000. If your account is below this limit you would need to call Customer Service to be able to request the Security Code Card.

Operation

Once you have both a Physical device and the IB Key app enabled, M2-FS is represented by a drop-down menu upon login. You can now choose the device you wish to authenticate with.

1. Enter your username and password into the trading platform² or Account Management login screen and click Login. If correct, a drop down option will allow you to Select Second Factor Device:
   
   TWS:
   
   
   Account Management:
   
    
2. Once you select a security device, you will now be presented with the corresponding screen for authentication. Refer to the directions for:
   
   - IB Key (iOS) 
   - IB Key (Android)
   - Security Code Card
   - Digital Security Card+
    
3. If authentication succeeds, the Log-in will now automatically proceed.
   
   TWS:
   
   
   Account Management:
   

2: Requires TWS Build 966 and above.

Withdrawal limits

The device used to authenticate your withdrawal, will dictate the withdrawal limit at that time. See details below:

3: Represents a legacy device that is no longer issued.

For example if you have both the IB Key app and the Digital Security Card+ enabled and need to withdrawal more than USD 200,000, you can use either device to login to Account Management but will be required to use the Digital Security Card+ to authenticate your withdrawal request.

Benefits

M2-FS provides even more flexibility to IB's Secure Login System by allowing you to choose what security device you want to authenticate with. In addition to the convenience of using a device which is trusted and routinely accessible, you can eliminate delays associated with authenticating at times a trade needs to be entered quickly.
