Storing password input using PS/2 keyboard

Hi,

The FPGA device contains volatile type memory which means once you power down, all the information is lost. Thus, if you need to store those information in a non-volatile type memory, then you would need to use a component/IP to access those flash memory in your project design.

Or hardcode it in the hardware description, it depends on what you want to use the password for but if it is a one-off design, or something that it is ok for if all devices have the same passcode it will work. If it is safe depends on what level of safety you want.
