I have found the best password managers to be, in order...
1) Sharp Memory
2) Self discipline
3) Prioritizing Security
4) Consistent execution and follow-through on personal security best practices
5) Personal Accountability
Sorry for the 4th one being so long but hey, it made the list so it must be good.
