Once i am using BTS 2.0 via a hosted web wallet and my keys are stored locally in my web browser, what happens if i clear my browser cache?
I'm guessing keys can be loaded into multiple browsers so as to have access from different devices without causing issues?
After you have created your wallet you want to create a backup.
As I understand it (devs chime in if I am off) it will be the similar type of tech wallet.bitshares.org uses.. so what you want to do is as soon as you have created your account, create a backup file. This will save you from browser cache erasure.
For other devices I would guess you can use that backup to then load into your other devices for us. (again devs can correct me if I am wrong)
