A quick follow-up on password thoughts. One extra thought on passwords is that no matter how good a password is for other reasons, if your fingers can’t type it, it quits being a good password! Test type your password a few times before committing to it.
An open question: is there ever a need for all-numeric passwords? Prior to smart phone days, cell phone passwords that were just numbers were far easier to type. If you have some such device, it’s probably worth having a standby, all numbers, password. A really old phone number, or phone number of an old friend, or some such, is a great choice here. By the way, this is pretty good for some WiFi encryption needs as well.
