Use the same security precautions as you would for online banking. In particular, do not sign in over public Wi-Fi. Keep your antivirus software active and up to date, and keep your web browser updated. Check that the sign-in page has not been replaced by a fake one. A closed padlock should appear next to the address, and the address should begin with https rather than http. You can check the SSL certificate for https://www.wirtualnebiura.pl/panelklienta/ by clicking the padlock. You may also follow any additional precautions recommended for online banking. We recommend changing your password at least once every three months. The customer panel is additionally protected by a one-time SMS code, so you may save your username and main password in your browser or another password manager for convenience.
