This is the one of the few apps I constantly recommend to my clients.
It is reliable-- I've never lost any data with it. It does a smart field by field comparison during synchronization if you also run it on other platforms, so if there is any conflict (maybe your internet service was offline and you updated the same entry differently on different devices) it smartly preserves both bits of data. It is secure-- it keeps everything encrypted under a master password using 448-bit key Blowfish encryption (which is very secure and allows for speed, light resource usage, as well as security.). It is robust-- I have almost 800 entries and it is still lightning quick to decrypt/open and synch. It is compact-- the database and interface do not contain unnecessary bloat; it takes up minimal screen real estate, drive space and resources. It is smart-- it is designed to accommodate any type of data, with or without categories, etc. and can even generate self-running web applets... so you can distribute a sub-set / separate encrypted database to give to clients or peers which doesn't even require the app to run. It doesn't utilize any plug-ins that can break with every browser update or cause instability or other issues. It is compatible--- it can synch with its iOS, Android and Windows counterparts. It is flexible-- the auto-typing feature can utilize special characters (definable through a small drop-down menu) to accommodate various website login formats (multiple page logins, etc.) It is fairly priced-- purchase the Mac app and the iOS app and both of these apps together still cost far less than the main Mac competitor alone.
It works like a Password manager should. Oh, and Sanford, the creator, offers quick and friendly support. Highly recommended.
