I am "fighting" with Dashlane password manager at the moment (again), and looking into other password management solutions. One that I have complete overlooked until now is Keychain. Am trying to learn about it and would like to look into actually using it. I think that what has been happening over the years is that I have inadvertently developed a "library" of sites, logins and passwords in Keychain that I have never used, never updated, and never culled. When I open Keychain I think I am seeing multiple entries for the same sites, sites I have no recollection of, and not having any entries for some of the sites I use. Is there a simple way to "erase" everything and start over? How would I go about that? I have looked at YouTube and haven't found that discussed. Likewise I have looked at the Apple Support Site and not seen anything promising. Thank you for any direction and suggestions.
