I'm not so sure this was intentional, as some people have speculated, nor do I see any evidence that a check was not previously in place. Remember when Dropbox allowed anyone to login to an account without a password? [0] That doesn't mean Dropbox never checked passwords, or intentionally dropped the check. Especially in the crypto space, iteration happens fast and bugs like this can come up. It seems pretty obvious that they not only had a defect, but did not have the appropriate monitoring, or alternating in place to identify the issue either. I try not to leave coin on exchanges due to hacking, bankruptcy, fraud, etc.<p>[0] <a href="https://www.cnet.com/news/dropbox-confirms-security-glitch-no-password-required/" rel="nofollow">https://www.cnet.com/news/dropbox-confirms-security-glitch-n...</a>
