Change the authentication frequency

If the MFA lifetime is shorter than your session expiration length, users with active sessions don't authenticate when their MFA expires.

HealthInsight task recommendation

In your Okta sign-on policy or app sign-on policy, shorten the amount of time that a user can be idle. Require users to provide MFA every time they sign in.

Okta recommends

To increase the authentication frequency for all resources, configure these conditions in your Okta sign-on policy:

  • Set your session expiration to a shorter duration

  • Require MFA at every sign-in attempt

To increase the authentication frequency for specific apps, create an app sign-on policy with your desired session length and MFA lifetimes.
