This article provides information about the lifetime of various factors and the steps to follow for setting up Multi-Factor Authentication (MFA) lifetime.

• MFA will be remembered for the device cookie. As long as the configured MFA lifetime for the device cookie is valid, users will not be prompted for MFA when signing in.

• Factor Lifetime
• Multi-Factor Authentication
• Okta Classic Engine

The MFA lifetime can be set up by performing the following:

1. Navigate to the Admin Console > Security menu > Authentication.
2. Select the Sign On tab.  Once this tab is open, there are a few options: 
   • To add a new policy and a corresponding new rule.
   • To add a new rule to an existing policy. 
   • To edit an existing rule. 

3. Regardless of choosing to edit an existing rule or to add a new one, once the rule is opened, the Policy settings section is available. At the end of this section,  there is a Multifactor authentication (MFA) part with two options available. Please select the Required option. 
4. The Users will be prompted for the MFA field to appear, with three options available. 
5. Select After MFA lifetime expires for the device cookie option, and the MFA lifetime section will become available. The default value is 15 minutes. By clicking on the field corresponding to the Minutes, it can be changed to Days or Hours, and by clicking on the field where 15 value is written, one can insert the desired value. 

6. Once the desired configuration is completed, click on Create rule or Update rule. The option available depends on what was chosen at point 2.
   
   The end user's experience when they log in, will see an option "Do not challenge me on this device for the next [X] minutes".
   
   In this example, since the MFA lifetime is configured to be 15 minutes, this will also be shown on the login screen.
