The best way to pick a secure password is according to the following steps:
Do not use a simple dictionary word but rather a combination of words or even better some random letters that you can remember
Choose both upper case and lower case letters
Include at least a single number
Include some non-alphanumeric characters such as “-“
A simple example of a bad password would be “snowman” which is a simple word; a good example of a password would be “_snow157man” which would be very difficult to guess.
