I prefer to back up to brainkey only. Is there a way for me to change my active key without a bin file backup? I have created a new account (local wallet) in the bitshares client, but when I get to step 3.2 above, and click save, it asks me to log in with my password and a bin file back up.

The only other option is for it to create a bin file back up as I save, but I do not want to do that.

Any other option for me?

It would be easier to just change the memo key, but that does not appear to be an option either...
