Haven't you ever forgotten a password? It's an awful feeling that you can now avoid by downloading 1Password to your iPhone, possibly one of the best password managers for mobile devices, although it also comes along with desktop versions.
You'll only have to remember a single password.
Your life protected with 1Password
As you already know, to increase the security of your email accounts, credit cards and any other service you use, it's recommendable to use different passwords, of a certain complexity, and that can't be related to any aspect of your life.
The consequence of all the latter is that it's impossible to be able to memorize so many codes. For such purpose, 1Password becomes essential when it comes to saving and using your passwords on different services, as you can save them all in this application and simply access them with a master key. That will be the only password you have to remember.
