Cause: Your target MCU does not support password-based readout protection.
Fix: Upgrade to a chip with a security coprocessor or use an external secure element.
As the Internet of Things (IoT) expands, simple password-based flash locking is being replaced by Physical Unclonable Functions (PUFs) and Trusted Execution Environments (TEEs). However, Tinybit-style passwords remain popular for:
Expect future versions of Tinybit tools to support password salting and rate-limiting to resist brute-force attacks better.
