The internet is a dangerous place with all sorts of shady people out to get your personal data. One of the best ways to keep your accounts secure is with 2-factor authentication.
The slight inconvenience is worth the effort. But just don’t get caught without your cellphone or you’ll be back to cumbersome codes again. This user likes the cumbersome codes, though. My opinion is that the easier we make authentication and verification, the easier it will be to breach it.
