Since the S7-1500 stores its configuration and password on the SIMATIC Memory Card , you can reset the password by clearing the card: Remove the SIMATIC Memory Card
For legitimate owners unable to access their equipment, Siemens technical support is an official avenue, though it has its challenges.
A critical technical detail for your planning: In manual version 14.14, it states: "The password for protection of confidential configuration data is retained after the CPU is reset to factory settings". Therefore, if you only need to clear the configuration password, you must look for the specific check-box option Delete password for protection of confidential PLC configuration data in STEP 7's online tools. Other protection types may require different, sometimes more destructive, methods.
If you are searching for a simple "password reset" tool or a backdoor password, you will be disappointed. Unlike older PLC generations (like the S7-300/400), the S7-1500 was designed with cybersecurity in mind. This means that Siemens has effectively removed the traditional "factory reset" capability that wipes the memory and clears passwords without authentication.
Siemens S7-1500 CPUs do not store a "backdoor" password. If the CPU access password or the project file password is lost, you cannot bypass or crack it through the TIA Portal software. You must reset the CPU hardware or clear the memory card. Method 1: The Factory Reset (No Password Required) siemens s7-1500 password reset

Resetting a Siemens S7-1500 Password: A Complete Guide Forgetting a password on a Siemens S7-1500 is a common headache for automation engineers. Whether you have lost the "Access Level" password or the "PLC Configuration Data" protection password, you can regain control of your hardware—though often at the cost of the existing program and data. 1. Using the PLC Display (Easiest Method)
Are you trying to recover a from the PLC, or do you have the original project and just need to clear the hardware?
Before performing a reset, it is vital to understand what you are dealing with. The S7-1500 implements multiple layers of security, and not all of them are affected equally by a "factory reset":
Resetting a Siemens S7-1500 password typically involves a factory reset, which will the current user program and configuration. Common Recovery Scenarios Other protection types may require different, sometimes more
the SIMATIC.S7S folder (or cut and paste it to your local PC desktop as a backup). Safely eject the SMC from your computer. Insert the SMC back into the powered-off S7-1500 CPU.
Imagine standing in a humming control cabinet, staring at the status LEDs on your Siemens S7-1500 PLC. You’re ready to upload new logic or troubleshoot a production issue, but the TIA Portal is asking for a password that you simply cannot remember. This is a moment of high anxiety for any automation engineer. The good news is that a forgotten password is not a permanent brick wall, but it is a significant hurdle that requires a clear understanding of Siemens' security architecture and a methodical approach to resolve.
