Occasionally, someone may create a very easy password, or one that would be simple to guess or crack.
When that happens, usually the site sends an alert to the administrators along the lines of:
High Severity Problems:
* User “XXXXXXX” with ‘subscriber’ access has a very easy password.
When we receive this, we will normally contact the person to ask them to change it. If it hasn’t been changed, then they will be logged out, and forced to reset. (This will mean your password will no longer work, and you will need to use the ‘Forgot Password’ function in order to generate yourself a new one).
