7640 all in one is asking for a passkey to print.

My Envy 7640 is suddenly asking for a passkey in order to print.  I have never used one.  Any ideas?

@svfarrow, Welcome to HP Support Community!

To provide you with an accurate solution, I would like to know the following-

Which application are you trying to print from?

Is the passkey request appearing on the PC or the Printer?

Are you able to make photocopies on the printer?

Meanwhile, reset the printer-

1. Turn the printer on, if it is not already on.
2. Wait until the printer is idle and silent before you continue.
3. With the printer turned on, disconnect the power cord from the rear of the printer.
4. Unplug the power cord from the wall outlet.
5. Wait at least 60 seconds.
6. Plug the power cord back into the wall outlet.
7. Reconnect the power cord to the rear of the printer.
8. Turn on the printer, if it does not automatically turn on.
9. Wait until the printer is idle and silent before you proceed.

Update the printer firmware

Download available firmware updates from the HP website

With the printer on and connected to the computer, go to HP Customer Support - Software and Driver Downloads, and then identify your printer. Look for and install any available firmware updates.

For more information, go to Updating or Upgrading Printer Firmware.
