Multifactor Authentication

Multifactor Authentication (MFA) is an added layer of security used to verify an end user's identity when they sign in to an application.

An Okta adminAn abbreviation of administrator. This is the individual(s) who have access to the Okta Administrator Dashboard. They control the provisioning and deprovisioning of end users, the assigning of apps, the resetting of passwords, and the overall end user experience. Only administrators have the Administration button on the upper right side of the My Applications page. can configure MFA at the organization level or application level. If both levels are enabled, end usersIn Okta literature, we generally refer to "end users" as the people who have their own Okta home page (My Applications), using chiclets to authenticate into all of their apps. End users do not have any administrative control. When we refer to "users" we are generally referring to the individual(s) who have administrative control. are prompted to confirm their credentials with factors both when signing in to Okta and when accessing an application.

  • YubiKey

    Using their USB connector, end users press on the YubiKey hard token to emit a new, one-time password to securely log into their accounts. Security is assured, as all YubiKey validation occurs within the Okta Cloud.

    ClosedAbout YubiKey

    Produced by Yubico, a YubiKey is a multifactor authentication device that delivers a unique password every time it's activated by an end-user. Using their USB connector, end-users simply press on the YubiKey hard token to emit a new, one-time password (OTP) to securely log into their accounts. Security is assured, as all YubiKey validation occurs within the Okta Cloud. As such, Okta guarantees Okta-level quality of service and uptime for YubiKey authentication.

    To specify YubiKey for authentication, the only task is to upload the YubiKey seed file, also known as the Configuration Secrets file. To create this file, follow the instructions below. Once uploaded, the screen verifies the number of successfully uploaded YubiKeys, and lists any errors that occurred in the process.

    ClosedCreate a YubiKey Configuration File

    Before you can enable the YubiKey integration as a multifactor authentication option, you need to obtain and upload a Configuration Secrets file generated through the Yubikey Personalization Tool. Find details on generating this file (which might also be called a Yubikey or Okta secrets file), in the Programming YubiKeys for Okta document. The Configuration Secrets file is a .csv that allows you to provide authorized YubiKeys to your org's end users. Yubico sends the requested number of "clean" hard tokens which, once setup is complete, you can distribute to your end-users.

    Be sure to read and follow the instructions found in Programming YubiKeys for Okta document very carefully. Once completed, follow the steps under Uploading into the Okta Platform found in Using YubiKey Authentication in Okta.

    With purchase of the YubiKeys, Yubico offers an additional premium service to create a secrets file on your behalf. Contact Yubico for details on this option.

    Troubleshooting

    If you encounter problems with generating your Configuration Secrets file or in configuring your Yubikeys, verify that you've satisfied the following questions and steps below.

    Did you select Configuration Slot 1?

    Each YubiKey is configured for the YubiCloud in Configuration Slot 1 by default. If you plan to use your Yubikeys for services other than Okta, you can use Slot 2 for Okta configuration. However, if you’re experiencing errors, it’s a best practice to use Configuration Slot 1 exclusively for Okta.

    Did you click the three Generate buttons?

    When going through the steps for configuring your Yubikeys, verify that you have clicked all three of the Generate buttons.

    Did you check your Generated OTP?

    An important step in checking your work is noting that the Public Identity value exists in your generated OTP. If it is not present, your Yubikey is not correctly configured.

    To check the file, do the following:

    1. Open the .csv file generated by the YubiKey Personalization Tool.
    2. Note the Public Identity value, listed as the second value item in the file.
    3. Open a text editor, then tap on the YubiKey that was configured for use with Okta. Allow YubiKey to generate the OTP within the text editor.
    4. Search for the aforementioned Public Identity value in the generated OTP. If it is not present in the line of text, the YubiKey has not been successfully configured.

    ClosedUsing a YubiKey

    Managing Tokens

    Now, with a successfully uploaded Configuration Secrets file, you can view all the unassigned YubiKeys available within your org. Your end-users should begin to enroll their individual tokens on their devices, and the assigned tokens should begin to appear in your reports.

    Viewing Your YubiKeys

    Click the View Report button to view a list containing the serial values of all your assigned and unassigned YubiKeys. Alternatively, you can find the same information from the Reports page, under the MFA Usage link.

    A report can be run at any time to view:

    • Active tokens (YubiKeys which are associated with users.)
    • Blocked tokens (YubiKeys which were once active, but are now either reset by the end user or the Okta admin.)
    • Unassigned tokens (An unassigned YubiKey has secret values uploaded and is ready to be self enrolled by an end-user.)
    • Names of assigned end-users

    Removing Lost, Stolen, or Invalid YubiKeys

    Another benefit of the YubiKey hard token is the ability to easily unauthorize users if it is ever lost or stolen—it is non-transferable and easily replaced. If an end-user reports their YubiKey as lost or stolen, you can remove these individual tokens using its unique serial number. This method is also the way to remove unassigned YubiKeys. Ensure the YubiKey has already been reset by following the Resetting MFA instructions. A YubiKey serial can not be removed if it is currently active for a user.

    From the Yubikey tab,

    1. Enter the serial number into the Revoke Yubikey Seed field.
    2. Click the Find Yubikey button.
    3. A Delete Yubikey modal appears to verify that you wish to permanently delete the YubiKey.
    4. A confirmation page appears. Click the Done button.

    Best Practice: If a lost YubiKey is found, it's a best practice to simply discard the old token. An admin can also reprogram the YubiKey by following the steps within the Programming Yubikeys for Okta file, which can be found in Configuring Yubikey Tokens. This generates a new Configuration Secrets file for upload, and allows the token to be re-enrolled by any end user within the Okta framework.

    The End-User Experience

    What happens for your end user? Enrollment is simple. When a user signs into Okta for the first time or after a reset, they will be prompted to choose an MFA option for their account. At this point, they can choose the Yubikey option.

    Once they click the Setup button, step-by-step instructions follow for successful registration.

    Enrollment Failure

    If an end user is unable to enroll their YubiKey successfully, ensure that the token was successfully uploaded into the Okta platform. Navigate to the Yubikey Report found on the Reports page. Search (by serial number) for the end user who is attempting to enroll.

    • If the YubiKey is present in the YubiKey report, and the status is unassigned, the end user has potentially reprogrammed their Yubikey and overwritten the secrets associated with the Yubikey. This requires the admin to follow the instructions found in the Programming Yubikeys for Okta file, which can be found in Configuring Yubikey Tokens, and upload again into the Okta platform.
    • If the Yubikey is not present in YubiKey report, then the Yubikey secrets value has not been properly uploaded and must be uploaded again into the Okta platform.

     

    Best Practice: If a Yubikey is decoupled from it's user, consider revoking the token from your system and reissuing the end user another unassigned Yubikey for enrollment.

    ClosedSupported Protocols and Communication Channels

    For successful YubiKey authentication, the following token modes are supported:

    • TOTP
    • U2F (Requires Google Chrome. Refer to the previous section for more information on U2F)

  • On-Prem MFA

    To sign in, end-users must use an RSA hardware dongle device or soft token to generate an authentication code to sign into your org. The numbers are generated using a built-in clock and the card's factory-encoded random key. The Okta On-Prem MFA agentA software agent is a lightweight program that runs as a service outside of Okta. It is typically installed behind a firewall and allows Okta to tunnel communication between an on-premises service and Okta's cloud service. Okta employs several agent types: Active Directory, LDAP, RADIUS, RSA, Active Directory Password Sync, and IWA. For example, users can install multiple Active Directory agents to ensure that the integration is robust and highly available across geographic locations. (formerly named the RSA SecurID agent) acts as a RADIUS clientEssentially, a client is anything that talks to the Okta service. Within the traditional client-server model, Okta is the server. The client might be an agent, an Okta mobile app, or a browser plugin. and will communicate with your RADIUS enabled on-prem MFA server, including RSA Authentication manager for RSA SecurIDs. For details about this option, see Configuring the On-Prem MFA Agent (including RSA SecurID).

    1. Select Setup.
    2. Choose a security question, enter an answer, and then click Save.

    The next time your users sign in, they are prompted to answer their security question.

    Security Questions Guidelines

    All the following guidelines are required for security questions:

    • The answer to a security question must be at least four characters long; however, a longer length can be specified for recovery flows in a Group Password Policy.
    • The answer to a security question cannot be the user's password or user name.
    • The answer to the security question cannot be included in the question.

     

  • Email

    End-users receive a code in an email message to enter during Okta sign in.

    ClosedUsing Email

    This is an Early Access feature. To enable it, please contact Okta Support.

    To select email as a factor, click the checkbox.

    Important notes:

    • Okta Mobile Android currently does not support email as an MFA factor.
    • Using email as a factor is not a best practice. When you add it as a factor, you must accept the risk of using it. The following message appears:

      We do not recommend that you use email as a second factor experience for Okta. This experience is a very insecure method of additional verification as:

      • Email can be compromised by third parties
      • Email is not always transmitted over secure protocols
      • Email can also be used, depending on the recovery flow, for primary credential recovery

      Although we do offer email as a factor experience for convenience and to help our customers migrate off of legacy identity platforms, we do not consider it to be a secure, modern method for secondary authentication. To continue enabling this feature, please click "I accept the risk" below.”

    After enabling email as a factor here, you must set the usage details and restrictions in a policy. Policies are described in the section below.

    ClosedSpecifications available in policies for email factors

    If you have authorized email as an authentication factor, it appears in the factor list for a policy. By default it is disabled. There are two options for the email factor, as follows:

    • Disabled – End users specified in this rule cannot use email for multifactor authentication.
    • Auto Enroll – End users specified by this rule are automatically enrolled in email factors based on their primary email addresses in their user profiles.

    Note: You can limit the use of email as a factor during password recovery.

    You can specify whether to allow email as an authentication factor in account recovery. Additionally, you can specify how long the code sent in an email is valid.


Enabling and resetting MFA

ClosedEnable MFA for admins

Super Admins can enable mandatory multi-factor authentication for all administrators signing into Okta Administration.

  • After this feature is enabled, the MFA policy for the Admin Dashboard will be enabled by default. The next time an admin logs in, they will be prompted to set up MFA for admins.

  • Administrators that have NOT enrolled into an existing MFA factor will be prompted to enroll for the first time.
  • At least ONE factor must be turned on for your organization to enable this setting. If the org does not have any MFA factors enabled, Okta Verify with one time passwords (OTP) will be enabled as the default factor. If factors have already been configured, then no changes will be made.
  • MFA for admins can only be set to enabled or disabled. It cannot be configured like other MFA policies.

  • It is recommended to never disable multifactor authentication for administrators. This decreases your overall security posture and increases risk for administrator accounts to be compromised.

To enable the setting, follow these steps:

  1. Navigate to Security > General.
  2. Scroll to Multifactor for Administrators.
  3. Click Edit.
  4. Select Enable Multifactor for Administrators.
  5. Click Save.
ClosedReset MFA for end users

In the event that you need to reset multifactor authentication for your end users, you can choose to reset configured factors for one or multiple users.

    ClosedSoftlock

    Our Softlock feature, available for password policies, are also available for delegated authentication. Active Directory (AD) and LDAP-mastered users will have a five attempts for MFA, after which the Okta account will be locked. The number of unsuccessful attempts before locking cannot be changed. It is fixed at five. AD-Mastered users can take advantage of the Okta Self Service feature, however, LDAP-mastered users require admin action to unlock their Okta account.

    ClosedThird-Party MFA Providers with Okta

    Okta's native Multifactor Authentication (MFA) method, Okta Verify, balances ease of use with security. However, sometimes circumstances dictate your choices. Feedback from hundreds of Okta customers currently using Okta for MFA, exposed a number of scenarios where a third-party MFA provider was needed. Some customers had a pre-existing investment in a legacy MFA provider and were wary of the cost and effort in changing their user experience. Others required the high-level assurance that hardware tokens can deliver for a subset of privileged users. Still others were in a state of transition—eager to adopt Okta Verify, but reluctant to migrate from their old provider too abruptly.

    While authentication methods do matter, they are only a part of the story with Okta. Our flexible policy framework, catalog of thousands of app integrations, and contextual access control allow our customers to broadly deploy MFA across their organizations. You are not restricted to Okta Verify—various third-party authentication methods are compatible and seamless with the Okta identity platform. Okta can even support multiple factors simultaneously, allowing organizations to migrate between factors or support heterogeneous user environments.

    This is why Okta expertly supports several third-party MFA providers. Click to view a table listing supported providers and details about their integration.
