The email address on your account cannot be changed by yourself because it is used as your login and is therefore locked for editing. Only an Administrator or Owner with access to Users & Teams can update user roles and permissions, but changing the email itself is not done through this panel.
If you need to update the email address associated with your account, you must contact your organisation's Administrator or Owner, or reach out to BriqSafe support. Changing the email address does not affect tasks already assigned to you; those remain linked to your account regardless of notifications.
Your email address controls where notifications are sent, so if the email is updated by Administrator or support, future notifications will be delivered to the new address, but existing task assignments and historical data stay unchanged.
