What not to do when choosing a password !
Do not choose a password based upon personal data like your name,surname or username, or other information that one could easily discover about you from such sources as searching the internet.
Do not choose a password that is a word (English or otherwise), proper name, name of a TV show, name of a singer, keyboard sequence, or anything else that one would expect a clever person to put in a "dictionary" of passwords.
Do not choose a password that is a simple transformation of a word, such as putting a punctuation mark at the beginning or end of a word, converting the letter "l" to the digit "1", writing a word backwards, etc. For example, "password,123" is not a good password, since adding ",123" is a common, simple transformation of a word.
Do not choose passwords less than 8 characters long or that are made up solely of numbers or letters. Use letters of different cases, mixtures of digits and letters, and/or non-alphanumeric characters. For example : R@Ih2k:Sa&J
Good post! Here are some more ideas...
Write it down and keep it in a safe. I go beyond the 16 minimum. Probably 25 or 30 maybe shorter if your data is really random. Just a simple habit like this puts you in total control of your money.
Over the years I have collected lots of random data sources I can copy in pieces but be very careful doing that. Add your own entropy to that data at least. Base 58 is nice because it leaves out some letters that look like numbers.
