When I first got on the 1Password train I was quite hesitant to fully commit and begin to change my passwords to improve security. Years later I am fully on board. Years of reliability have built enough confidence so that all my new logins are created solely with 1Password. I have even went back and changed most if not all my old logins.
It doesnt end there however. 100% of my software licenses and registration keys are stored in 1Password as well.
Wifi sync is absolutely great. I am not a fan of the idea of storing passwords in the cloud. Wifi syncing to my Mac leaves me pleased I theres no single point of failure that could cause me headache. Wifi supports Windows as well if youre into that sort of thing.
One Time Password support makes this an absolute necessity.
