It does make logins on other machines difficult. You may open up your password manager's web interface on your friends laptop, but then you opened up all your passwords to potential malware,including banks etc. When you just wanted to log in to Reddit, where you have an account you somewhat care about: you spent years under that username, but its not a huge catastrophe if it's taken away, unlike, say, your domain registrations, your email password, your e-government logins, banks etc. The "all eggs in one basket" still bothers me.
