Unlock CoDeSys v3.5 Project & Library Password
Recover a project or library password in CODESYS V3.5, the newer XML-based generation of the platform from 3S-Smart Software Solutions, built around the Library Manager with versioned, namespaced libraries. This covers user-rights and project passwords — CODESYS V3.5 separately supports protecting a project with a USB security key instead of (or alongside) a password, which is a different mechanism and not something this service covers. If you'd rather have it handled, I provide manual CODESYS recovery support — done personally, with nothing sold or downloaded from this site.

Who does the recovery?
I do, personally. Every job is manual — it isn't automated with a tool and it isn't resold to anyone else.
Do I have to own the equipment?
Yes. I only help owners and authorized maintainers regain access to their own projects — in line with the authorized-use-only policy on the channel.
Do you sell a tool or a download for this?
No. There are no tools for sale and no downloads on this site. Recovery is a manual service I perform or guide you through.
