Apple released a security update for macOS 10.15.xx (Catalina) and 11.xx (Big Sur). If you have any of these macOS versions and you use the Okta Device Registration Task, device enrollment failures may occur. This may result in users not being able to access applications that are protected by the Okta Device Trust policy. It may also result in a Keychain Access prompt.
Here’s a link to Okta’s public-facing wiki.
