No, OpaqueID’s are just temporary ID’s and belong to no one
OpaqueID can and will change at will.
I have observed:
- Loads page, has OpaqueID ( a )
- Grants, has OpaqueID ( b )
- Ungrants, has OpaqueID ( c )
There is not and should not be a way to a link OpaqueID to TwitchID as then you are tracking users before they granted. This might have changed but that is the behaviour I have observed. OpaqueID’s change at will.
