Unlock CoDeSys v2.3 Project Password & Library (.LIB) Protection

1:47 · Published Jun 2026

Platform: CODESYS

Recover a project or library password in CODESYS V2.3, the older generation of the platform from 3S-Smart Software Solutions, built around binary .PRO project files and a shared .LIB library folder — architecturally distinct from the newer V3.5 line. If you'd rather have it handled, I provide manual CODESYS recovery support — done personally, with nothing sold or downloaded from this site.

What this walkthrough covers

  • Project / safety password recovery
  • Write-protection password recovery
  • User password recovery
  • .LIB library file unlock

Supported software & hardware

  • CODESYS V2.3 (3S-Smart Software Solutions)
  • Project (.PRO) and library (.LIB) files

Who this is for

  • You forgot or lost the password on your own CODESYS V2.3 project
  • A previous engineer left and no password record was kept
  • You've inherited a locked legacy CODESYS V2.3 project you legally own
  • You need to open or edit a protected .LIB library file for maintenance

Locked out of a CODESYS project you own?

Send the software and version, and a short description of what you're locked out of. The work is manual and done personally — no tools sold, no downloads.
