Regarding the management of private data and passwords it is clear that the undisputed king for many years is 1Password, but being an app with a high price for many people it was a simple matter of time before some other app gained market share as OneSafe is doing.
Prettier, less functional
The visual aspect of the application is impeccable, far surpassing the 3Password version 1, which is the one that can be purchased today for Mac. All the details are well cared for and it shows that the graphic design team has invested many hours in making the application a delight for the eyes.
As for the possibilities you have to be coherent and say that it is behind the AgileBits app. 1Password something that OneSafe does not give us and that for many is essential: extensions in browsers to make instant login. It's possibly what I use the most and that's why it's what keeps me away from 1Password at the moment.
The price of the Mac version is 12 euros, while 1Password is going at 45 on the Mac App Store. A noticeable difference for an app that is not as far as the price indicates.
