Signals Notebook: What is the impact of editing the Email address of a user

Please find the points below that would be impacted while updating Email addresses of users:

• Changing a user's email address will remove all API keys assigned to that user on all domains.
   
• In the case that the user exists in different tenants, then the email address for that particular user need to be updated in the other tenants to avoid the log in fail while trying logging in using the new email address.
