Cloud accounts · Adding an account
How do I add a second account right after the first one?
Short answer: When you see Account added, click Add Another. The form clears for the next account; click Done when you've finished. Every account stays signed in separately.
When the sheet shows the green check and Account added, click Add Another. The form clears so you can pick the next account type and nickname straight away; click Done when you've finished.
Each account is signed in and stored separately, and they all stay connected at the same time. For Google, the account chooser always appears, so you can pick a different account even if you're already signed in to one in your browser — see more than one Google Drive account.
