CB 4.4.1.23 router login/password

Running Comodo Backup 4.4.1.23. I’m backing up to removable storage connected to my password protected router. My backup kicks off at 0200 and when I get up at 0500 I find a pop up in Comodo asking for router login/password. Any way to save this so I do not need to manually input each time I want to run a backup? Thanks.
