Just like the title says. I don't have a phone of my own, so I'm planning to use my mom's phone to grab the code or whatever.
So yeah, I'm just wondering a few more things:
1. How do I deactivate it in case something goes wrong (i.e. Computer is taken over by a virus that targets compooters, not Steam)
2. I don't always have access to my main PC (or rather family's) due to siblings. Can I still trade if I have to use my toaster laptop?
3. If I get a new PC, how can I transfer confirmations and such over to my new one?
Will add more questions as they come up.
