I haven't had to do that in a few years now. But if I did, well, that's what having the phone is good for. A hassle to type out the password, but better than not having it at all. They don't have to be long to be a strong password either, something like $80nS)t*plV#9 is short, strong, but won't drive you crazy to type out manually.
That would drive me crazy to type out manually.
