General SSO Questions

What is "SSO"? How did I end up there?
"SSO" stands for "Single Sign-On" and it allows you to use your STScI SSO Portal credentials to log on to many services throughout the Institute. Rather than have each service maintain separate user accounts, users log in through the SSO Portal. This should all happen seamlessly in the background. A primary benefit is that you will only need to remember one user name and password.
How long do I stay authenticated?
An active connection can last for up to 10 hours. An idle session will expire after 4 hours. If you log into an SSO application your session will expire in 4 hours. If during that 4 hours you access that or another SSO application, your expiration time will be extended for another 4 hours, up to a total of 10 hours. Please note that some services have additional security needs requiring users to re-authenticate during the 10 hour SSO window.
What happens when the 10 hour activity timer expires?
You will be forwarded to the SSO Portal Login page, since your session has expired and you'll have to restart the clock by logging in, which sets up your first 4-hour sliding window.
I am logging in with the correct information, and I can't log in. What should I do?
It is possible your account has been locked. After 5 failed log in attempts, your account is locked for 15 minutes. This is a necessary security measure. If you need to have your account unlocked, you can wait 15 minutes and try logging in again or please contact support@stsci.edu and let them know you need your account unlocked. Provide as much information as possible, including your first name, last name, current and any previous email address you may have used with the system.
I cannot access the application I'm trying to log into. What can I do?
Please contact support@stsci.edu and provide as much information as possible, including the application you are trying to access, your first name, last name, current and any previous email address you may have used with the system.
