Use Account → Security in the sidebar to manage sign-in email, password, and account deletion.
Cockpit sends a confirmation message to the new address. You must open the link in that email to complete the change; until then, the update may not be fully applied.
While the request runs, you may see an updating state. On success, a confirmation message is shown. If the passwords do not match or validation fails, the form shows the corresponding error before submitting.
The Account deletion section explains that requesting deletion starts a process where your account will be removed within a defined period (as stated in the product copy), after which login is no longer possible and data is permanently removed. This action cannot be undone.
If you are unsure, export personal data or transfer organization ownership before deleting the account.
