The OPC Collector should allow us to add username and password through the .ocf file. We are generating the .ocf file through automation scripts as we have a lot of tags (100,000+). This freezes up the OPC Collector tile and doesn't allow us to add the password. 

Canary can read the password once from the .ocf file on startup and then rewrite it with the encrypted string. This way the password string will remain secure.

If this can be done it will allow us to fully generate the .ocf files and not enter anything manually into the OPC Collector tile.
