I'm having trouble understanding something about step 3 about. It says,
"In the "Identity" section at the top, enter your secret key.
Click "Set Identity" - after entering the passphrase, it will display your
public key / wallet address on top of the "show/hide secret" button."

Wasn't the whole point so that we wouldn't have to type the secret key with an online computer? Doesn't doing so in this step make the wallet vulnerable to key loggers, etc?

Any clarification would be greatly appreciated. I'm new to all of this and still trying to wrap my head around it. And thank you very much for this informative article.
