Forgot admin password for M452nw EWS admin portal

RBITC · ‎08-24-2026

I need to factory restore a Color LaserJet Pro M452nw printer.

I know its IP address for the EWS but have no record of the password.

The default password does not work.

Hello @RBITC, Welcome to the HP Support Community.

Since the HP Color LaserJet Pro M452nw is an older model, its EWS security works differently from newer LaserJet models. The M452 user guide confirms that the EWS administrator password is set under System > Administration > Product Security.

To factory reset your HP Color LaserJet Pro M452nw when you do not know the EWS password, you must use the physical control panel on the printer itself.

Locating the Default PIN (Alternative)

If you try to access the HP Embedded Web Server (EWS) again after the reset, note that newer firmware versions do not use a blank password or "admin". Look for a sticker/label inside the cartridge access door or front door which lists a factory-default PIN or password.
