Using Okta FastPass boosts the security of the organization and offers a great experience for the end-users, as they are not required to keep re-entering their password each time they authenticate. However, this passwordless authentication may have as a downside the fact that users may be at risk of forgetting their account's password.

This article describes the Password Re-authentication Frequency setting, which helps in preventing users from forgetting their passwords. 
 

• Okta Identity Engine (OIE)
• Multi-factor Authentication (MFA)
• Re-authentication Frequency

Steps to setup Password Re-authentication Frequency: 

1. From the Okta Admin Console, navigate to Security > Authentication Policy.
2. From the policies available, select the desired policy.
3. Once selected, there are the options to either edit an existing rule or to add a new rule. 
4. Scroll down on the rule that just opened until Password Re-authentication Frequency field is visible. 
5. By default, the value of this field is 2 hours. This value can be changed to as many minutes, hours, or days is desired. 
6. Click Save.
