Magento doesn’t store passwords directly, it stores a hash. The same is probably true for WooCommerce. You wouldn’t be able to re-hash the password but you may be able to tweak Woo’s hashing logic to match Magento’s. I would avoid this though, password resets aren’t very burdensome and even give you an excuse to engage with customers. The rest you can probably migrate.
