If you have problems with passwords, then I suggest checking LastPass. LastPass is known to be a very secure solution when it comes to keeping passwords in one place. The software supports mobile platforms and two-step verification to keep hackers out of your account. You are recommended to use it with your browser. I have been using it for almost 3-4 years and it worked correctly all the time. After installation, the software presents tutorials with video support for better understanding of its work.
