Problem: The client is developing a website and needs to know if granting FTP access to a third-party for support could compromise the WPML license key. Solution: We assure you that the WPML license key is securely stored in the database and is not accessible via FTP/SFTP. Granting a developer FTP access does not compromise the security of the license key, as it is bound to your domain and cannot be used elsewhere. Furthermore, the translations are also stored in the database and do not depend on the WPML key. If necessary, you can remove and regenerate a new WPML key for your domain from here.
If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. Should you need further assistance, please do not hesitate to open a new support ticket at WPML support forum.
