Change admin email wp without email confirmation

Updating via functions.php in active theme:

You could set one time code (and delete it after) in functions.php of your active theme to update these options:

update_option( 'admin_email', 'admin@example.com' );
update_option( 'new_admin_email', 'admin@example.com' ); 

Put these within some admin_init action callback.
