1Password 4 adds Watchtower website security monitoring
Watchtower is off by default, so you'll need to pay a visit to 1Password's preferences to enable it. Once active, it downloads a database to cross reference against your logins and adds a red alert bar to entries for potential problem sites. Agile Bits says all checking is done through 1Password on your Mac, so no personal information is transmitted back to their servers.
The 4.4 update also improved conflict resolution during syncing, added Greek localization, fixed several bugs, and more.
1Password 4 is priced at US$49.99 and is available for download through the Mac App Store and at the Agile Bits website. The 4.4 update is free, as is the Watchtower service.
