Begin by visiting classlink.lcusd.net and on the login page, enter your username (first part of LCUSD or mylcusd email address, ex. jbauer24 for students or mmouse for staff).
Next, enter your school password and click sign in (do not use sign in with Google yet).
After hitting sign in, look to the top right and click on the profile picture. This might be just a blank face if you are a new user. Then click on MY PROFILE.
Next, select SIGN IN OPTIONS
Click on the blue CONNECT button next to the Google account option. A window will open and select your school email address. You will then see a red success window. Close that and close the MY PROFILE window. Going forward, you can now login using the SIGN IN WITH GOOGLE button or with username and password. Both work.
