One account is a comprehensive financial service platform, which is usually provided by banks or other financial institutions. One-code-pass account integrates various financial services functions such as bank account, securities account and capital account. Users can log in and manage multiple financial products through a unified account. This integration helps to improve the user's convenience and reduce the complexity of managing multiple financial accounts.
A securities account is an account specially used for securities trading. Securities accounts are usually provided by securities companies to record and manage the information of investors buying and selling securities products such as stocks, bonds and funds. The difference between a securities account and a one-code account is that it is only used for securities trading and does not involve other financial businesses.
In short, the one-code account is an integrated financial service platform, which integrates various financial accounts, and the securities account is an account specially used for securities trading. Although both involve financial business, their emphases and application fields are different.
