How to Add Accounts in Google Inbox

Google Inbox was an email management app that has been discontinued by Google. However, if you're referring to Gmail, which is Google's email service, here's how you can add accounts:

1. Open Gmail in your web browser and sign in to your account.

2. Click on your profile picture or initial located in the top-right corner of the screen.

3. Select "Add another account" from the dropdown menu.

4. Enter the email address and password for the account you want to add, and click "Next".

5. If two-factor authentication is enabled on the account you're adding, follow the prompts to enter the verification code.

6. Once the account is added, you can switch between accounts by clicking on your profile picture or initial and selecting the account you want to switch to from the dropdown menu.

7. You can also access all your accounts simultaneously by clicking on the "Gmail" logo located in the top-left corner of the screen and selecting the account you want to switch to from the dropdown menu.

Repeat these steps for each account you want to add to your Gmail.
