Hi Apple Community, Problem : Should be able to use my iDP password when I try to unlock my macOS local User Account.
 Password should sync across my macOS local User Account, when my User Account Password in iDP Changed
 Should have a provision to create a on-demand macOS local account with password of iDP Should be able to Create Primary Account in Automated Device Enrollment with password synced to iDP ( Simplified PSSO in Setup Assistant ) Solution : These can be solved if the Identity Provider implements Platform SSO , but not being implemented by all major Identity Providers Except major iDPs like Okta, Microsoft, Ping 
Since Platform SSO Offers the necessary framework and provision that satisfy the above needs I planned to make a open-source initiative to bridge in PSSO and Oauth ROPG to connect with Any OpenID Provider that supports Oauth ROPG 
I KNOW PSSO DOESN’T MEANT FOR THIS AND NEEDS TO BE IMPLEMENTED BY IDP, AND MEANINGFUL SSO TOKENS CAN BE ONLY ISSUED BY THEM TO HELP THE SSO EXTENSION 
But the native login Experience, FileVault Synchronization, Keychain Unlock everything being handled by OS in PSSO. I thought its best to go in this way The Attachment Includes the Components, Design Decisions of this Project , Questions in the PSSO Framework workflow. Including some Questions from new WWDC26 OpenID Authentication Method introduced in PlatformSSO Please help with the Questions in the Attachment and post if there is any suggestions on the workflow I described Filed Feedback with FB23065453

Hi Apple Community & Apple Team,

Since Platform SSO Offers the necessary framework and provision that satisfy the above needs I planned to make a open-source initiative to bridge in PSSO and Oauth ROPG to connect with Any OpenID Provider that supports Oauth ROPG ( Resource Owner Password Grant ) 
ITS RIGHT THAT PSSO DOESN’T MEANT FOR THIS AND NEEDS TO BE IMPLEMENTED BY IDENTITY PROVIDER, AND MEANINGFUL ID TOKENS CAN BE ONLY USED BY THEM TO HELP THE SSO EXTENSION 
But the native login Experience, FileVault Synchronization, Keychain Unlock everything being handled by OS in PSSO.
