Password Managers Apps
With more and more services requesting that you make an account popping up seemingly every month, and all of them recommending that you use unique passwords that aren’t used on other services (good advice, of course!), trying to keep track of them all can quickly become overwhelming. That’s one of the main reasons that password managers such as LastPass and 1Password have become as popular as they have.
These password management apps will allow you to securely store all of the different passwords you use for the multitude of services you use in your daily life, with no need to remember crazy and complex combinations.
