Today, we released Alfred v2.0.8 in anticipation of Agilebits' 1Password 4 release. Those using the beta version of 1Password 4 will be able to use Alfred's 1Password 1Click Bookmarks integration right away. Non-beta users will need to exercise patience just a little longer until version 4 is officially released :)
To take advantage of this feature, you'll need to enable integration in 1Password 4's preferences as shown in the screenshot below.
This integration only shows your 1Click bookmarks, as it did in version 3. Your data remains completely safe and protected by 1Password's usual great security features, so activating this feature won't put your data at risk.
