How do I change my email or add a sign-in method?

Use the account's sign-in-management flow to change your email or add a sign-in method. Calsa asks for a fresh sign-in before a sensitive change. A new email becomes active only after you confirm the new address. Adding another provider also requires proof of ownership.

For an email change, the confirmation lasts one hour. Your previous address receives a notice with a This wasn't me recovery link. Review the resulting methods before relying on the new one, and never send support a sign-in code to make the change for you.
