I don’t know what will happen to 1Password but it seems that it will go for the membership only option some time in the near future. This is how I understand the linked post.
Ben Brooks from The Brooks review:
I’ve read this post several times now and all I can say is this: they are hell bent on pushing people to 1Password.com — just look at the amount of “yet” phrasing used throughout. I’m going to start looking elsewhere. Not interested.
There are three “yets” in the post.
I will wait to see what will happen to 1Password. Maybe I will choose the membership, who knows.
But I know one thing: I depend on 1Password because it generates every password I use when I start to use a new service.
