import to keychain from roboform

I am trying to put passwords into the simplest manager to make it easier for my wife to use passwords after I die. [Not a joke. I am 80 and in very poor health.] She becomes very frustrated when trying to logon a financial web site. I am culling my passwords from 100+ to 50 or under. I want to make passwords easy to use so Keychain, a native app instead of using a third-party app. Simplicity is key. Thanks a lot.
