DUO authentication is slow or timing out on macOS

Tags duo mac macos ESET

DUO Two-Factor authenntication can time out, loop, or load extrememly slowly on MacOS devices when ESET Endpoint Antivirus is not configured correctly for Web and Email security. This is typically observed in Google Chrome.


When attempting to login to anything that requires DUO Two-Factor authentication on an LSA managed MacOS device with ESET Endpoint Antivirus installed using Google Chrome, the shiboleth (weblogin.umich.edu) and 2-factor pages can take as much as 10 minutes to load, and will often fail or timeout, causing an authentication request loop.


  • MacOS (Apple)
  • ESET Endpoint Antivirus
  • Google Chrome
  • Weblogin
  • DUO Two-Factor Authentication


This issue is caused by a misconfigured ESET Endpoint Antivirus client. The Web and Email protection options should be disabled.


  1. Open the ESET client from the menubar icon in the upper right by clicking Open ESET Endpoint Antivirus
  2. Click the Web and Email icon 
  3. Ensure that the following options are Disabled
    • Web access protection
    • Email client protection
