This is the inverse of this question here.
Google keeps prompting me to enable Two-Factor Authentication for my Google account. I don't like the inconvenience of TFA, such as mandating that I will always have my mobile device handy on me. Assuming that I have a secure (i.e. reasonably long and complex) password that isn't likely to cracked by the most high-end consumer hardware for at least the next decade, can I get away with keeping TFA off?
