I read an interview with Matt Davey in which he recommended changing one's passwords every ninety days. This seems like sensible advice, but I was wondering if this also applied to one's Master Password. Unlike one's other passwords, one actually has to memorize this, and it seems like a bit of work to memorize a new password or passphrase every ninety days. (Perhaps I just have a poor memory.)
In a nutshell, then, my question is this: how often should one change one's Master Password?
