LastPass for Premium Customers lets you keep all of your passwords and other sensitive account information in one place for easy access. With all of your log-ins and other data stored in this app, you won't need to remember all of your individual passwords, and you'll always have them on hand when you need to log in to a site.
Autofill: Once you've entered your account information into this app, you can use it to autofill your log-ins and other data into online forms. With just a few taps, you'll be in, so you can enter your data into this app once and never worry about typing it out again.
Password Generator: In addition to storing your passwords, this app can also create them for you. Using the Password Generator, you can decide how long the password should be, what characters to include, and whether you want the password to be pronounceable, among other things.
Sync across devices: When you set up your LastPass Premium account on one device, you can automatically sync it across all of your devices as long as you have the app installed. That saves you from having to record your log-ins on multiple devices and makes it possible for you to access all of your accounts quickly, no matter what device you're using.
Incomplete tutorial: When you first open the app, a tutorial takes you through the process of adding your first site. But once that's done, the tutorial is abruptly over, and you're left to figure out the rest of the app on your own. It would be nice if there was a bit more guidance available to help set up the app more thoroughly.
LastPass for Premium Customers offers a nice set of features to make it easy to generate secure passwords and store them securely, so you can log in to all of your online accounts quickly. Some extra guidance during the setup process would be welcome, but the interface is intuitive enough that it's not really necessary. The app itself is free, and it comes with a 14-day free trial of the Premium service, which regularly costs $11.99 per year and is available via in-app purchase.
