Being prompted to enter my account password more often than expected on my Chromebook

I'm using a Chromebook with the 1Password extension enabled. I get an "authentication required" pop up every few hours, even while constantly using the device (with no reboots or having the device go to sleep). The browser will also automatically pop to the sign in page. I've followed the remove-reinstall as well as the Settings/Integrate with desktop app instructions with no significant improvement. If I understand the long string of messages above, this is a Chrome OS problem? The pop-up only started in the last couple of weeks and I've been using the Chromebook and 1Password for a year now. Anything else I should understand?
