1. I have my keychain on my iPhone, so I can always look up the password there.

2. 1Password lets you publish an encrypted HTML viewer which you can share via Dropbox, so I can retrieve passwords online if need be (just need to remember my Dropbox and 1Password passwords).

Most users would have a smartphone or other device with 1Password or their password manager of choice on it, so you can copy the password manually from that device. I tend not to log in on any device that isn't mine, though.
