Why is multi-factor authentication needed?
Other way to compare the speed is to use Cisco AnyConnect and do the above. This allows an organization to evaluate the overall speed in the aforementioned baseline. For the or in the higher bandwidth, Cisco AnyConnect uses DTLS, will GlobalProtect also do the same or is it still the IPSec as the recommended option for the speed?

As organizations digitize operations and take on greater liability for storing customer data, the risks and need for security increase. Because attackers have long exploited user login data to gain entry to critical systems, verifying user identity has become essential.
Authentication based on usernames and passwords alone is unreliable and unwieldy, since users may have trouble storing, remembering, and managing them across multiple accounts, and many reuse passwords across services and create passwords that lack complexity. Passwords also offer weak security because of the ease of acquiring them through hacking, phishing, and malware.
What are examples of multi-factor authentication?
The most common example of MFA is the process for using an ATM at a bank. To gain access to their accounts, users must insert a bank card (a physical factor) and enter a PIN (a knowledge factor).
Another familiar example is the time-based one-time password (TOTP) method, used by financial institutions and other large enterprises to secure workflows, applications, and accounts. Upon requesting login, users are asked to provide a temporary passcode that has been sent via a text message, phone call, or email.
How does multi-factor authentication work?
MFA requires means of verification that unauthorized users won't have. Since passwords are insufficient for verifying identity, MFA requires multiple pieces of evidence to verify identity. The most common variant of MFA is two-factor authentication (2FA). The theory is that even if threat actors can impersonate a user with one piece of evidence, they won't be able to provide two or more.
Proper multi-factor authentication uses factors from at least two different categories. Using two from the same category does not fulfill the objective of MFA. Despite wide use of the password/security question combination, both factors are from the knowledge category--and don't qualify as MFA. A password and a temporary passcode qualify because the passcode is a possession factor, verifying ownership of a specific email account or mobile device.
Is multi-factor authentication complicated to use?
Multi-factor authentication introduces an extra step or two during the login process, but it is not complicated. The security industry is creating solutions to streamline the MFA process, and authentication technology is becoming more intuitive as it evolves.
For example, biometric factors like fingerprints and face scans offer fast, reliable logins. New technologies that leverage mobile device features like GPS, cameras, and microphones as authentication factors promise to further improve the identity verification process. Simple methods like push notifications only require a single tap to a user's smart phone or smart watch to verify their identity.
How do organizations start using MFA?
Many operating systems, service providers, and account-based platforms have incorporated MFA into their security settings. For single users or small businesses, using MFA is as simple as going to settings for operating systems, web platforms, and service providers and enabling the features.
Larger organizations with their own network portals and complex user-management challenges may need to use an authentication app like Duo, which adds an extra authentication step during login.
How do MFA and single sign-on (SSO) differ?
MFA is a security enhancement, while SSO is a system for improving productivity by allowing users to use one set of login credentials to access multiple systems and applications that previously may have each required their own logins.
While SSO works in conjunction with MFA, it does not replace it. Companies may require SSO--so corporate email names are used to log in--in addition to multi-factor authentication. SSO authenticates users with MFA and then, using software tokens, shares the authentication with multiple applications.
What is adaptive authentication?
In adaptive authentication, authentication rules continuously adjust based on the following variables:
- By user or groups of users defined by role, responsibility, or department
- By authentication method: for example, to authenticate users via push notification but not SMS
- By application: to enforce more secure MFA methods--such as push notification or Universal 2nd Factor (U2F)--for high-risk applications and services
- By geographic location: to restrict access to company resources based on a user's physical location, or to set conditional policies restricting use of certain authentication methods in some locations but not others
- By network information: to use network-in-use IP information as an authentication factor and to block authentication attempts from anonymous networks like Tor, proxies, and VPNs
Contact your system administrator if you have an issue that isn't listed here.
I need to reactivate Duo Mobile
If you get a new phone you'll need to re-activate Duo Mobile. You may enroll your new device yourself using Duo's device management portal if self-service is enabled. Otherwise, ask your administrator to send you a new activation link.
Choose your platform on the left for specific activation instructions.
If your administrator enabled Duo Mobile's backup and restore functionality and you previously backed up your Duo Mobile accounts then you can restore your accounts to Duo Mobile on your new phone (same platform as the original device i.e. Android to Android and iOS to iOS) via the guided recovery process. See the full Duo Restore guide here.
I have stopped receiving push notifications on Duo Mobile.
You may have trouble receiving push requests if there are network issues between your phone and our service. Many phones have trouble determining whether to use the WiFi or cellular data channel when checking for push requests, and simply turning the phone to airplane mode and back to normal operating mode again often resolves these sort of issues, if there is a reliable internet connection available. Similarly, the issue may be resolved by turning off the WiFi connection on your device and using the cellular data connection.
Check the time and date on your phone and make sure they are correct. If the date and time on your phone are manually set, try changing your device's configuration to sync date and time automatically with the network.
iOS users can run a troubleshooting tool from within Duo Mobile version 3.32.0 or later. To run the tool:
- Open the Duo Mobile app on your iOS device and tap the Edit button in the top left of the accounts list screen, then tap the name of the account for you aren't receiving push requests.
- Next, tap the Get Started button in the 'Missing Notifications?' section of the the 'Account Details' screen.
- Duo Mobile performs the test. If any step fails, you'll receive further troubleshooting suggestions. After taking the suggested actions, tap **Run test again* to retry.
The steps that Push Troubleshooting performs automatically are as follows:
- Check device settings.
- Check internet connectivity.
- Check that the device can contact Duo's cloud service.
- Attempts to send a test Duo Push notification.
Should none of these actions help, see the Duo Knowledge Base for additional iOS and Android troubleshooting steps.
If you can't get Duo Push working on your own and your administrator has enabled Duo's device management portal, you can log in with a passcode generated by the Duo Mobile app and send a new activation link to your phone. See the My Settings & Devices guide for instructions.
If you've tried the suggestions here but can't get Duo Push working or reactivate your device yourself, please contact your organization's Duo administrator to request reactivation of Duo Mobile.
I lost my phone.
Contact your Duo administrator immediately if you lose your phone or suspect that it's been stolen!
If your organization enabled Duo's self-service feature and you had previously enrolled a second authentication device you can use My Settings & Devices to delete your lost or stolen phone.
If you aren't able to log in to Duo at all then your Duo administrator can disable the missing phone for authentication and help you log in using another method.
While it's important that you contact your administrator if you lose your phone, remember that your password will still protect your account.
I use Duo Mobile to generate passcodes for services like Instagram and Facebook, and I can't log in.
You can use Duo Mobile to generate passcodes for use with third-party services like Instagram, Facebook, Snapchat, and others. When setting this up, you likely logged into those sites, visited the security settings for your account, and scanned a barcode provided by that site with Duo Mobile.
Duo does not have access to your third-party accounts or account credentials, so our Support Team is unable to help if you become locked out of these accounts.
If the application provided recovery codes to you when you enabled two-factor authentication, use a recovery code to log into the application, then visit the security settings where you first set up 2FA to restore Duo Mobile passcode access.
If you previously enabled Duo Restore for third-party accounts and made a backup, you can restore the account to your device.
If you don't have a Duo Mobile backup to restore or you experience some other issue logging in, please refer to the documentation for the application you're trying to log in to or contact the support team for that application for more help.
See the article What do I do if I’m locked out of Instagram, Facebook, or another third-party Duo Mobile account? in the Duo Knowledge Base for additional information.
My hardware token stopped working.
Contact your administrator if your token stops working or if you can't log in with the passcodes it generates.
Your token can get 'out of sync' if the button is pressed too many times in a row and the generated passcodes aren't used for login. In some cases this can happen by accident if the token is stored next to other objects in a pocket, backpack, etc. Your administrator will ask you to generate three passcodes in a row and can attempt to resynchronize the token.
I am running iOS 10 and I am not able to install the current version of Duo Mobile from the App Store on my device.
The minimum supported operating system version for Duo Mobile 3.29.0 and above is iOS 11.
iOS 10 users may download the last Duo Mobile version compatible with that iOS version (3.28.1) via Apple's TestFlight program.
- You'll need to install the Apple TestFlight application on your device.
- Once you have TestFlight installed, tap this link and then tap Install to install Duo Mobile 3.28.1 on your iOS 10 device.
Contact your administrator if further assistance is required.
