How To Calculate Entropy?
H, I've been lurking for quite some time now and am totally new to password management systems and the like. I wanted to ask how does one calculate entropy? Is there a formula you could share for both word based and randomly generated character passwords? How much entropy is enough entropy for my master password or any password for that matter. I just used the randomly generated word based suggestions (4 words) for mine as all my passwords before entering the realm of password systems were extremely basic, like my birthday for example.
Also to follow up, 1Password has the strength meter that I'm sure many of us are familiar with, where exactly on that meter is strong enough. Bright green? On the other hand, what is too little? Where do all the colors rank?
Really love 1Password by the way, very happy with it and can recommend it to anyone, I tried a bunch of different ones but I feel that this is the best option overall for anyone and the amazing customer support doesn't go unnoticed.
