If Oregon does the same thing Washington does, it allows you to print a replacement ballot using the online system which can then be mailed back or dropped off. Looking at the /pol/ thread someone posted above, this appears to be the case:
>he can change who he voted for
>these can be changed, printed off, and dropped off at any courthouse with NO ID REQUIRED AT ANY STAGE
This is exactly what the WA online system does, and WA's system invalidates the original ballot that was mailed to you when you do this.
The only authentication (again, for WA; I don't know about OR) is the voter signs the ballot envelope, and the election office compares that to a copy of the voter's signature which they keep on file...which can be updated by mailing in a form with an updated signature without providing them any verification of identity that you are who you claim to be.
