Who you are to this panel. Applications keep their own logins and passwords and are not affected.
Your own address. Saving a new one sends it a link to confirm it; once confirmed it is where a link to reset your password can go. A domain's report address can be filled with it from Domain settings.
Needed only to change the e-mail.
To this address, when something needs you: a DNS record of a domain stops matching, a rate limit refuses mail, the TLS certificate is about to expire, a message has waited in the queue for three days. What is sent and when
A link was sent to mix@example.org at 14:02; it works once, for 24 hours.
Changing it signs out every other session of this account; this one stays signed in.
