Security guidelines

We recommend that you follow these guidelines at all times.

• Use Log out (centered at the top of the page) to exit.
• End your session properly.
• Do not leave your computer unattended when a session is open.
• Erase your computer's cache memory.
  The cache, or temporary memory, may be labelled under a variety of names depending on the operating system. It is usually stored in the temporary files, which are generally accessible through your browser. Consult your software supplier if you do not know how to erase your browser's cache memory.
• Close the browser.
  Closing your browser is the simplest and most secure way of ending your session. Provided your browser is set up in this way, it deletes all copies of Web pages stored on your hard drive, which ensures that your data cannot be accessed.
• Never disclose your identity validation data.
  Do not disclose any data used to validate your identity, including your access code, user code and password. Should a breach of confidentiality occur, please notify our client services immediately to prevent fraudulent use of your identity.
• Beware of fraudulent email.
  Revenu Québec never requests confidential information by regular email. Any such requests are placed in the secure electronic mail box that is assigned along with each user code. Be suspicious of any email from a sender that claims to be Revenu Québec.
• Check the URL address.
  The URL address, or Web address, is shown in the address bar of your browser at the top of the screen. This address begins with https on secure sites.  
• Protect your computer.
  We recommend installing a firewall on your computer. A firewall filters the information coming from the Internet and prevents unauthorized access to your computer. We also recommend installing anti-virus software to reduce the risk of infection via the Internet. Anti-virus software can detect viruses and clean your computer.
