When it comes to online safety and passwords, I live and die by a password manager. I use one on my PCs, as well as my Android smartphones and tablets. This way, I always have my passwords with me, and I only have to remember one (to get into the password manager). In fact, I've never even seen some of my passwords when I use a generator.
If this is the type of secure password storage you need in your life, look no further than Handy Apps' new Password Wallet. Exactly as its name implies, Password Wallet is a safe, secure, digital locker for all of your passwords.
