Firstly, think of a word or two. They can be whatever you like, I have chosen the words "Grilled Cheese"
Subsequently, add upper and lower case letters. This makes Grilled Cheese turn into GrIlLeD cHeEsE
Now, add numbers. It is easier to add them where it is easier to remember. Now Grilled Cheese is GrI113D cH33s3
Now to finish your password, add some unusual characters. Now Grilled Cheese has finally become GrI113D_cH33s3
Make sure you can remember your password, you can write it down if you want. And remember! Always use the same password, its harder to forget that way!
