Not sure this is the right part of the forums to ask this kind of question...

However, in order to answer it then you'll need to explain what portal software you're using!

The most likely answer is that you can reset the password via some built-in mechanism (e.g. it emails you a new one), or edit it manually in the database (on the assumption that the user system is database driven - most likely is); of course, worth pointing out that most decent systems wouldn't store your password in plain text, so you'd also need to know the encryption/hashing method used so that you can replicate it for your new password etc.
