If you are at Brown and have requested a regular CCV account, your Oscar login can be authenticated using your Brown credentials itself, i.e. the same username and password that you use to login to any Brown service such as "canvas".
If it is a temporary guest account (e.g. as part of a class), you should have been provided with a username of the format "guestxxx" along with a password.
If you are an external user, you will have to get a sponsored ID at Brown through the department with which you are associated, before requesting an account on Oscar. Once you have the sponsored ID at Brown, you can request an account on Oscar and use your Brown username and password to login.
Oscar users should use their Brown passwords to log into Oscar except very few legacy user accounts. To change your Brown password, go to myaccount.brown.edu to do it.
To change your Oscar login password for a legacy user account, use the command:
You will be asked to enter your old password, then your new password twice.

minimum length: 8 characters

at least 3 characters should be different from the previous password
