The “remember me” option is displayed by Duo when you sign in with FDU NetID on the web. After providing your second factor for authentication, Duo will present you with a prompt asking if you would like to have this device remembered for future logins. Selecting “Yes, this is my device” sets the “remember me” status for Duo.

Use the “remember me” option to reduce how often you have to sign in with two-factor authentication (2FA) on the same web browser. It’s safe to use on trusted computers and lasts for 30 days.

Refer to our Duo Quick Start Guide below for instructions on using the “remember me” option within the context of the overall sign-in experience.

Use “remember me” on trusted computers

The “remember me” option is safe to use on computers and devices that you can trust to protect your browser. Examples include managed workstations at work, lab computers that require you to sign in, and personal computers, laptops, tablets, and mobile devices that protect your browser from use by others.

Do not use “remember me” on public or shared computers Do not use “remember me” on public or shared computers

The “remember me” option shouldn’t be used on computers and devices that don’t protect your browser, such as public or shared computers, and computers you don’t sign in to and cannot lock to protect your browser.


What is the “remember me” option?

The “remember me” option is a feature of Duo that tells your browser to remember that you have confirmed your identity using your 2FA device. If you confirm that “Yes, this is my device” when authenticating with Duo, you won’t have to use your 2FA device as often on that browser. For example, if you use it on your computer at work, it reduces how often you have to sign in with 2FA at work; but your laptop at home will still ask you to sign in with 2FA.

Why would I want to use it?

The “remember me” option saves you time and reduces distraction by reducing how often you have to use your 2FA device. If you routinely use the Duo callback method, it also saves the FDU money in telephony costs.

Is “Remember Me” safe? Doesn’t it defeat the purpose of 2FA?

The “remember me” option is safe to use on computers and devices that you can trust to protect your browser. It doesn’t defeat the purpose of 2FA because the convenience it provides is limited to each computer and browser that you choose to use it on. If you or anyone else tries to sign in with your FDU NetID on a different computer or browser, 2FA will be required.

How long does it last?

The “remember me” option lasts 30 days. It saves a secure cookie on your browser to track the time until you need to use your 2FA device again. If your browser clears cookies this will remove “remember me” until you re-select it.

Why is the “remember me” duration 30 days?

30 days is the current “remember me” duration because it is often enough to remind you that 2FA is turned on, but not so often to be annoying. While some institutions use shorter or longer durations, 30 days is a common duration at peer institutions.

How do I clear it on my current browser?

If the “remember me” option is enabled on the browser you’re using right now, clear your cookies for To clear it on other browsers, repeat this process on each of them.

How do I reset it on a browser I no longer control?

If you enabled the “remember me” option on a browser you no longer control, Please open a support ticket by clicking Support at the top of the page, or visiting


When FDU IT resets your “remember me”, it will clear it on all your browsers, including those you no longer control. Once it has been reset, you can enable it again on your current browser(s).


I’m using the “remember me” option, and I still have to use my 2FA device more often than every 30 days. Why is that?

Some system owners require you to reauthenticate with 2FA every time you access their systems for security, regardless of using the “remember me” option (workday for example). This can increase how often you have to sign in with 2FA. If you find you are regularly asked for 2FA on some sites despite the “remember me” option, but not other websites this is likely the cause. Other contributing factors include how many different computers you use, how many different browsers you use on these computers, whether or not you use the “remember me” option on all of them, how your browsers are configured to use cookies, and how often you clear your browser cookies.

Why do some system owners override the “remember me” option and reauthenticate me every time I sign in?

System owners decide to reauthenticate you based on what institutional and personal data they need to protect, and what threats and risks they need to guard against. Some of them reauthenticate you because they are concerned about unauthorized access from unattended browser sessions, and forcing you to reauthenticate is one way to re-establish that it’s you.

Why isn’t the “remember me” option working for me? Are there things that prevent it from working correctly?
