Can Android Chrome be linked to an account other than your main Android account? Say that your main Android account is account1@gmail.com. Can you set up Android Chrome to use account2@gmail.com?

(Ideally Chrome would allow multiple users, which will no doubt happen in Android too eventually.)
Launch Chrome


In the overflow menu, choose Settings
Under basics, tap the entry for your account
Disconnect the account; you'll be warned that the data will remain but you'll lose your synchronization
Tap Sign in to Chrome at the bottom of the screen
Choose the account you want to use for synchronizing


Obviously for this to work you will need to have already added the account to your phone.
