LastPass is one of those must-have Android apps. It’s a password manager that lets you save your login credentials in a safe, secure way.

It has cross-platform support so you can use it on computers, mobile devices, tablets, or whatever.
There are others, but LastPass always feels like it’s one step ahead. Additionally, the premium version is cheap. You can also grab LastPass Authenticator to go along with it for added security.
