Unwarranted paranoia.<p>The worst thing that can happen here is that somebody connects to your wifi. If someone can read your email and is in the vicinity to connect to your wifi, the least of your problems is that he or she does connect to your wifi.<p>Also, as pointed out by others, this doesn't mean it's stored in plain text. Any time you set a password it travels in plain text (typically - and hopefully - via a secure connection) and it arrives to their server in plain text. You are never sure they are immediately storing it properly encrypted in a DB. They can also be doing things like sending it in emails or storing it elsewhere. If you cannot trust your password to whoever is storing it you are basically f<i></i>*ed. BTW, what do you think they might do whenever you enter the wrong password in the wrong site? (for instance, your email password).
