If you are a KCL user with a Rosalind account then you can use your KCL username and password to access the system. If you forget your password, or would like to change it, then you should do this through KCL IT, as normal. If you haven't already signed up to their self-service password reset system, then you can do that here: http://kclpword.kcl.ac.uk/

Passwords for non-KCL users are managed by the FreeIPA server on the Rosalind system. If you would like to change your password, you can do so from the HPC login nodes as follows:

# authenticate to the server
kinit
<current password>

# request password change
ipa user-mod <username> --password

If you do not have access to the HPC login nodes, either because you have a Cloud-only account or because you have forgotten your password, please contact your Rosalind Systems Administrator to have it reset.
