Account & security
Display name vs login email
You can rename how you appear. You cannot casually change the email that owns the account.
Keep this page — the product described here is what the exchange actually runs.
Display name
Settings → Account. This is a label. It is not your login. It can be changed whenever you want.
Login email
This is the identity of the account. It is not self-editable in Settings. If you need it changed (for example, a typo), contact support from that mailbox and be ready to pass security checks. We will not swap email to an address we cannot prove you control.
Confirming email
If Settings shows a verification code flow, complete it. Confirming email is for your recovery, not for marketing.
