I think you're referring to PAKE (password-authenticated key exchange). SRP (secure remote protocol) might be the Stanford proposal you're referring to, although it's actually fairly commonly implemented as far as PAKEs go (Apple for instance uses it for their iCloud Keychain).

This is it, thanks. PAKE. No wonder I couldn’t remember it!
