Always dump the original BIOS before making changes. A bricked Unowhy Y13 requires a heat gun and a soldering iron, which is the opposite of portable.
Warning: Do not type random master passwords 20 times. This can permanently brick the TPM (Trusted Platform Module) on the Y13. Legally: If you own the device, yes. If you are a school technician with a lost master password, yes. Ethically: If you bought a stolen Unowhy Y13 from eBay, no. These laptops have MDM (Mobile Device Management) locks that may auto-re-lock when connected to Wi-Fi. Bypassing the BIOS does not bypass the Wicoms Cloud Lock . unowhy+y13+bios+password+portable
