Terms & Conditions

Password policy

We require users to follow good password management practice as described in their institutions policies.

Passwords are set to a certain standard:

  1. At least one uppercase letter
  2. At least one lowercase letter
  3. At least one number digit
  4. Password length is at least 8 characters

If a number of attempts to login to the systems fail, then this may trigger automatic banning from your computer for 24 hours.

Password changes to the systems can be performed via the mySCW interface.

Best Practice

Please also see our page on Conduct & Best Practice.


Users and projects that are inactive (no logins and/or no compute activity) for more than 12 months may be disabled as a security measure. Reactivation is easily achieved through contacting the Support Desk.
