After logging into classlink.lcusd.net and connecting your Google account, it's time to store some passwords for accounts you use often.
Click on a app you wish to store the password for and you'll see a prompt to enter your username and password. Fill in the requested information and hit save. You will then see a new tab open, something will read Making the Magic happen (resist the urge to press the X on that window), and you should now be logged into that app.
Quick recap: once you store the password via classlink.lcusd.net, you will now be able to just click the app and get in.
One note of caution, some of you may have used Chrome to save passwords. While not bad, that may autofill the app login page with incorrect data. Be sure to clear out anything that jumps in automatically in yellow highlight. If you accidentally clicked save and the app opens but you are them prompted again to enter your password, you'll need to access the password locker under my profile to either edit or delete the stored data and then reenter. More about that process here. This is also how you'd fix a saved password that you've changed or updated.
