I am looking for a new authenticator app and want one that is a separate app (not combined in a password manager like Apple's current solution). Looking at 2FAS but understand that Advanced Data Protection (ADP) for iCloud backups has not yet been implemented -- but may do so imminently. I also understand that Entre Auth and Proton Authenticator provide E2EE via their servers but require a login account in order to sync. Are there any apps that utilize iCloud ADP encryption by default without the need to create an account with a third party?
