Happy owner of an iPhone and eavy user of Keepass, I was looking for some application which performs the same job: keep an encrypted container of passwords. If you check on iTunes App Store, there are several applications “keepass-alike” but it’s not convenient to maintain two databases (duplicate information).
But… it seems that a Keepass port to the iPhone is on the way! It should be called “iKeepass”. Check the blog (RSS feed).
