Hi, in one of the posts i found here (cant find it, the credits for the original idea came from that person here in steemit) said that a solid password easy to remember was one with four words, lets say: caballo onion raton supermarket.
I took the idea and went for more, why? because you have more than one account in emails, social networks, other sites that require user and password; its dangerous to use the same password in all of them. Lets return to the base: caballo onion raton supermarket, you remember those 4 easily but how do i remember a new set of 4 word in other sites?
Do this: Set a rule that applies using your initial 4 words adding numbers, letters, simbols in positions or places you only know. For example for every 4 letters add numbers or last letter of the site: caba1lloonio2nrato3nsupe4rmarket, cabh1alloonih2onratoh1nsupermarkeh2t, and so on using rules you set so youll always remember it no matter how complex it is.
Hope this helps you as i already changed my old passwords for this method and worked perfectly, most important of all.. I remember each one no matter what account im logging in!!!
Hope this helps you too
