Yes, you can initially use your personal work email to re-authenticate your Tern account and later choose a different email for the scheduler. Start by re-authenticating using your personal work email. Then, go to User Settings, scroll to Email and Scheduling, disconnect your current account, and connect your preferred email for scheduling. Note that you can only connect one calendar at a time for scheduling. During setup, you have the option to connect for both email syncing and calendar scheduling, or just the scheduler.
