Consolidating emails gmail
Want to use both of your Gmail accounts through your new account?
This is the option for you—and if it works, it's the best way to move to a new Gmail account. If you run into a wall, abandon it and try option two.
20) Paste either your Google account password or app password into the password field, depending on which you used in the last section. Gmail will send a confirmation code to your old email address.
Open your old Gmail account again, find the confirmation email from Google, and copy the confirmation code—then switch back to your button in Gmail, and you can now choose to send emails from your old or your new Gmail address.
When you switch back to the second account, you get responses in your first Gmail account…HELP!
(We strongly recommend the first option just in case—unless you're almost out of storage in the old account, which could cause issues when forwarding.) 5) Save your changes.
9) Click the gear icon, then click Troubleshooting: If the system repeatedly tells you that you’ve entered the wrong username and/or password—but you’re certain that you’ve entered it correctly—it’s erroring because you either have two-step verification enabled on your old account or because Google believes the attempt to access the account is malicious.
The easiest way to resolve the problem is to enable two-step verification (if you haven’t already) and create an app password.
Here's how to combine multiple Gmail accounts into one, and get all of your email, calendar events, and contacts in one place.
