* Why does Affinity need to maintain access to my data?
  * This allows us to continually sync your email/calendar data to provide you with the most up-to-date metrics.
* What does it mean when Affinity reads my emails, calendars, and profile?
  * This allows Affinity to confirm your identity, set up your account, and surface your email/calendar data in a format that's easy to read.
* Why would Affinity send mail as myself?
  * This allows you to send outbound emails directly from Affinity - recipients will see that the email is from **you**.
  * We do **not** have access to your password and we cannot create, update, delete any emails, attachments, folders, and contacts from your account.

## Important Callouts

* You can only sign into Affinity with your email credentials. You **cannot** create a custom password for Affinity.
* When signing in via Office 365, you may encounter the following screen with two options. The most common and recommended option is to select **Work or school account**.
