Applications in the "Requires Additional Login" section are not directly integrated with Okta. You will need to log in with your Puget Sound credentials each time you access the app.
Some applications, such as Wells Fargo CEO, work in conjunction with the Okta Browser Plugin to log you in with different credentials. When you first launch the app, you will be prompted to Sign In To App and enter the credentials you use for that specific system. After clicking Sign In, the app will launch in a new browser tab and securely post the stored credentials over SSL. Each subsequent time you access the app, you will not need to enter your username/password to log in to the system.
If the password you use for the specific system changes, you will need to update the stored credentials. Simply click the three dots (∙∙∙) in the app tile on your dashboard, click Edit, enter the new information, then click Save. Credentials are securely stored with AES encryption coupled with a private key to ensure that nobody, even administrators, can see your password in plain text.
