The feature is available to Dropbox for Teams users
Dropbox is unveiling one more feature that Google had first – simultaneous logins: you can now stay logged into your regular Dropbox account and your Dropbox for Teams account at the same time.This should make it easier for those that use Dropbox at work or at school to switch between their personal and Teams accounts.
"Just click on your name in the top right corner, select 'Switch Accounts,' and sign into your other Dropbox account," Dropbox explained.
"Then, you’ll be able to flip easily between accounts by selecting the account from the drop-down menu, without having to sign in again during your session," it added.
The feature hasn't been rolled out to all users, it seems, so don't fret if you don't see the "switch accounts" link just yet. It's only available on the website, not on the mobile or desktop apps.
This only works between one personal account and a Teams one, not between two personal accounts. Signing out of Dropbox will sign you out of both accounts at a time.
