Security and usability are always at the opposite end of the spectrum. Balance it wisely.

This is such a dangerous false dichotomy. Plenty of security systems benefit user experience.

And in fact some systems are only usable because of their security. A bank that gives all accounts the same password could hardly be considered usable, neither could many websites if they did the same.
