Again, this is only a guess, but the first one is one time passwords. Don't disclose anything you may use consistently on your own network. Centainly I would never use repeated sign-ins. Hackers would love that. You've just given them another shot at your usual passwords. Multiple accounts isn't going to help much if you use the same password for all. Different computers won't help either if you use your normal password. One time passwords for me is the answer to the first blank.
The second blank is a bit easier. I think the answer is secure. Most good sites like Brainly use https (s for secure) and it is secure. When staying in a motel, you sometimes have to use http just to get on. As far as I know, Microsoft is the only site where that can be done.
