Lenovo Forums stores plaintext password as a cookie
As long as it's a http only secure cookie... it should not be a huge issue. Session ids are basically replacement for username+password anyway, and nobody cares they're stored in a cookie. Server knows the plaintext password already, too.So the only remaining issues are security issues around sharing your computer with other people, or programs. I guess stealing a session id is mildly less problematic than stealing the password in case the password is re-used elsewhere.
