We are currently using the legacy OID2 service from Google to partially authenticate users in the account recovery service that we have developed and supported. I understand that we need to switch to the new OpenID Connect service from Google before April 20, 2015. Part of the migration involves matching our old OID2 hashes (which we saved as unique and considered constant identifiers) to the new available sub_id value in the new service. We understand that providing the openid_realm value to the new service will give us our OID2 hashes from the openid_id value so that we can then map the new sub_id. Since we force users to check their account recovery settings annually, we can force them to authenticate with Google at that time. Considering,Since the time frame for migration is less than a year, it will be difficult to complete the full migration until April 15, 2015. To our question, how long will the value of openid_id in the new service return the old OID2 hashes for our area? Will he continue to continue closing the OID2 service?
