I copied this from the LastPass site. It works. I may try it for other unruly sites. Proof again that if it bugs you, someone has likely already solved it.
- I got frustrated enough with UPS.com's multiple-page login (seemingly) not working with lastpass, that I put a little effort into figuring it out. It almost works perfectly (few caveats).
Go to: https://www.ups.com/one-to-one/login?loc=en_US (change "en_US" to your language and country codes if applicable. For example, "fr_CA" would be for French Canadian)
Type in your username and then choose Save All Entered Data from your LastPass toolbar (this is where you say to yourself, "yeah, yeah... heard it before. But keep reading")
Click OK
Now go to your LastPass again and edit the site you just saved.
Delete every field except "uid"
Click Add Field
Enter "password" for name
Select "Password" for Field Type
Enter "passCollect" for Form Name
Click OK
Type in your password into the newly created password fieldord field
