<div class="markdown_content"><p>Hi everyone,</p> <p>I forgot the Administrator credentials for my local Soft PLC (CODESYS Control Win V3x64) running on CODESYS V3.5 SP22 Patch 2 (Windows 11).</p> <p>When I try to login/connect to the device, it asks for the Device User Management username and password.</p> <p>I checked the CODESYSControl.cfg file, which points the working directory to:<br/> Windows.WorkingDirectory=%APPDATA%\CODESYS\CODESYSControlWinV3x64\905D4E32</p> <p>However, I cannot locate the actual database/credentials files in AppData or ProgramData to clear them, and resetting the runtime directory doesn't seem to clear the authentication prompt.</p> <p>Could anyone please advise the correct steps to completely reset or wipe the User Management credentials for the Control Win V3.5 SP22 runtime?</p> <p>Thank you in advance!</p></div>
