How to switch between multiple accounts in Evernote for Mac or Windows
If you have multiple Evernote accounts (at least one of which must be Evernote Premium), you can easily switch between them in Evernote for Mac or Windows without having to sign out and sign back in each time.
Whenever you switch from one account to another, the Evernote app screen reloads and displays the other account with all of its notes and notebooks. You’ll find the Add Account... option in the Evernote menu. You can also use the shortcuts Ctrl + Cmd + A (Mac) or Ctrl + Alt + A (Windows) on your keyboard to quickly switch between accounts.
If you prefer to be prompted for your password each time you sign in to Evernote, you can sign out at the end of each session. The next time you open Evernote, you will be prompted for your username and password.
