What is a requirement for the email address used in Sage Accounting?

The requirement for the email address used in Sage Accounting being valid for login purposes is essential for ensuring that users can access their accounts securely and consistently. A valid email address serves as a unique identifier for the user and is integral to the authentication process. This means that users will need to enter a correctly formatted email address that is capable of receiving communications from Sage, as this may include password recovery options and important account notifications.

Using a temporary address would not support ongoing access and would lead to complications if users need to reset their passwords or receive important updates. Similarly, personal domains and random addresses may not guarantee validity or reliability in receiving important account-related messages, which further emphasizes why having a valid email is crucial.
