Yes, moving over to a new email address can be a exercise in itself, but done once, hopefully doesn’t need to be done again.
Something which can help you manage this is to use a password manager. While it doesn’t change your email address in itself, what it allows you to do is have a listing of all your logins where you can systematically go down the list changing contact details. A similar process is required when you move house or say get a new mobile number.
