Usernames are automatically assigned based on an individual's "preferred" name, as listed on the My Cal Poly Portal, under the Personal Info tab > My Info. An algorithm determines usernames based on availability. Usually, a username is created from a combination of your first initial and last name (up to eight characters). Users cannot personally choose their Cal Poly usernames and cannot have more than one active username.
The algorithm creates a username based on the following:
First initial, last name
Last name only
First initial, middle initial, last name
First two letters of first name, last name
Or a combination of the above, plus numbers
