Let's Find Out...about alternate IDs!
An alternate ID is a name you can use in place of your library card number when authenticating with our different library services (using a self-check machine, logging in to your library account, etc.).
I like to think of an alternate ID like entering your phone number at King Soopers instead of your Sooper card number. It's an easier way to remember your account login and allows you to use your account without having the physical card.
Creation and modification of alternate IDs is done only through the classic catalog. To start, log into the classic catalog with your library card number and PIN. Once you've logged in, select "modify personal information." A screen will pop up that will allow you to create or edit your alternate ID and email address. Both of these fields are optional. 
Alternate IDs must be unique (just like you!). They must contain alphanumeric characters and be between 6 and 25 characters in length.
You don't have to use an alternate ID, but I think they are a great option and once you set it up, you don't have to touch it again! I use mine all the time so if you're ready, log in to the classic catalog and add yours too.
***Note: You cannot use your Bibliocommons (the main catalog) username in place of your library card number in any places except logging in to your Bibliocommons library account. That username was created for using the features of Bibliocommons only. You CAN use your alternate ID to log in to Bibliocommons though.
