Hi everyone.

Thanks in advance for your help, and apologies if this question was covered elsewhere.

My graduate school uses Duo for authentication. When I log into the intranet on my laptop, I'm prompted to send a "push" notification to my phone. There's the option to "remember this device for 30 days", referring in this case to my laptop. But even when I check the box, I'm asked again to authenticate via phone each time I use the intranet on my laptop, seemingly despite having sought to "remember this device" previously. This is inconvenient, as I'm frequently without my phone.

How can I get the "remember" feature to take effect?

Again, thanks for your help -- and apologies for any indelicacies in my attempted description of the situation.

Detail like websites remembering you and log you in automatically is stored in a cookie.

You can use these steps to make a website recognize and remember you.

  • create a cookie allow exception with the proper protocol (https:// or http://) to make a website remember you

You can check that you aren't clearing important cookies.

  • using "Delete cookies and site data when Firefox is closed" keeps cookies with an allow exception
  • using "Clear history when Firefox closes" to clear cookies clears all cookies including cookies with an allow exception you may want to keep
  • clearing "Site Preferences" clears exceptions for cookies, images, pop-up windows, and software installation and exceptions for passwords and other website specific data
  • Settings -> Privacy & Security
    Cookies and Site Data: "Manage Exceptions/Permissions"

In case you use "Clear history when Firefox closes" or otherwise clear history.

  • do not clear the Cookies
  • do not clear the Site Preferences
  • clearing "Site Preferences" clears exceptions for cookies, images, pop-up windows, and software installation and exceptions for passwords and other website specific data
  • clearing "Cookies" will remove all cookies including cookies with an allow exception you may want to keep
