users won’t be able to login with their old password if it’s considered insecure. By default Discourse requires a minimum password length of 10 chars (for admins it’s 15) and the password must not be on the [list of common passwords][common_passwords]. But users can always reset their password by clicking the “I forgot my password” link on the login dialog or directly by visiting https://discourse.example.com/password-reset
