Ability to change email address associated with account is needed
The email used to make it was abandoned and it's now been compromised. That was used to reset my password and deactivate my account along with at least one of my users accounts. Luckily I was awake and actively using fedi when this happened so no real damage was done.
Users need the ability to change their email addresses and just see what addresses are on their accounts now that password resetting can be done through email. This is potentially a pretty big security issue.
