Remember Me issues

The first time you approve the Duo authentication request, you'll see the option to confirm the device is yours. This creates a trusted browser session that will let you skip Duo two-factor authentication when you log in again with the same browser and device until that trust session expires. You are still required to authenticate with your NetID and Password each time and your remembered device acts as a confirmation of your identity. Please note that this feature is a browser specific and not shared between different browsers. For example if you login with Chrome today and use Firefox later, it will ask you to authenticate again.

Do not select that this is your device when using a public or shared computer! This could leave your Duo session available to other users. Trust the browser only when you access applications from your own computer. Clicking on No, other people use this device will not create a trust session. You won't be asked to trust that device again for 14 days.

The Remember Me feature relies on cookies and when enabled correctly, you will not be asked to complete two-factor authentication the next time you are on the same browser. Please be aware of the following restrictions that can impact Remember Me feature and adjust your settings as necessary:

Chrome incognito does not provide support for Remember Me as cookies are cleared at the end of the session.

Internet Explorer has a “Delete browsing history on exit” in its General setting. If this is enabled, the Remember Me feature will not work.

Some browsers may have restricted security settings to only allow cookies from authorized sites. If so, please add add “duosecurity.com” as a trusted site.
