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.
