This video provides a detailed demonstration of how to bind multiple accounts to the same email address on the Instagram platform for unified management. The tutorial begins with logging into the main account, then guides users step-by-step through the 'Add Account' feature to create a new account, rather than logging into an existing one. The entire operation process requires first entering the profile page, clicking the menu in the upper right corner to access settings, and then scrolling to the bottom to select the 'Add Account' option. The video specifically emphasizes that Instagram currently supports a maximum of 5 accounts associated with one email address, and new accounts created will automatically inherit the email information of the currently logged-in account. After creating the account, users can quickly switch between multiple accounts by clicking on the account name, enabling efficient multi-account management. For users who need to manage multiple Instagram brand accounts, business accounts, or personal accounts simultaneously, this is a very practical account management tip that can significantly improve work efficiency and simplify the login process.
