This is a central login for all of your supporting accounts. Once you pair your account with your device, you won’t need to use their app to access their resources which will slim things down. One common example will be Google. Once you authenticate yourself with Google, you would have your Google Contacts synched with your Senitrus account. Senitrus Mail ( Internet > Mail ) will also allow you to synch your Gmail account therefore reducing the need to use a browser, or a web app. Another example will be Microsoft. Some file synching services such as Dropbox will hopefully work with Senitrus Systems, and integrate with the OS. By offering a means to add one or more accounts will give each Dropbox Account with letter (Such as F:/). This will allow you to treat your Dropbox service as if it was a local device. The Dropbox account will automatically unmount when you’re not connected to the internet.
Some providers might require that you go through additional hoops to prove you’re not a robot. If so, you would have to decide if it is worth linking them with your accounts. However, assuming that you do, they will give you all of the benefits you would expect from the service depending on the services they offer. If it is just mail, then setting up the account will automatically add to the Senitrus Mail App. An online drive will give a low letter ID, and so on. You can also add social networks which will also be in the accounts section. Since all of your accounts are in one place, you don’t have to go looking around if you need to modify or delete an account.
