This gets a little more tricky if you have an unexpired session but want to be able to change your password (which likely requires knowing the existing password), but a request from this logged in session to reset your password should be trustable (unless your "friends" have also stolen your unlocked device).
Similarly, if one or more of your "friends" requests a token / password reset of your acccount, the site should highlight that in a banner on every page you visit, to potentially give you warning to find better friends. (The process for replacing a friend on the site should probably require re-entering your password too, to stop someone that's hijacked your session from picking three sock puppet accounts as your new friends, and resetting your password that way).
