Being a person that has a MacBook and an iPhone, I love Keychain.
Being able to seamlessly create a strong password on any website or app I sign up to (depending on whether the service allows you to) is incredible.
But I have 1 or 2 gripes with it which I think would make it perfect for more people
1. Apple should create something on Windows that allows you to access or even just auto-fill your password on a Windows machine, I can’t think of how many times I game on my PC and want to log into something. Having to take out my phone, go through the process of finding the password and typing it out which becomes a chore. On Apple devices it works so I don’t think about it, which then frustrates me when I use Windows.
2. There are times when I want to create a strong password for a website or app I’m signing up to, but they don’t support it. I can’t just go into Keychain enter the website, username/e-mail and have it create a strong password for me. It leaves me jumping through hoops by creating the account with a simple password and then resetting the password just so I can create a strong password
