This is a situation where I actually like to "log in with Google"... - The information Google gives to the merchant is usually the same that I'd give the merchant anyway to make a purchase even if I wasn't making an account, assuming Google is being truthful when telling me what information it transmits. - I don't need to worry about whether the merchant properly hashes passwords. - If my Google account gets closed, it doesn't matter, assuming my goal was to not have an account with the merchant in the first place. - It's at least as frictionless.
