General SSO Questions

"SSO" stands for "Single Sign-On" and it allows you to use your STScI SSO credentials to log on to most services at the Institute. Rather than have each service maintain separate user accounts, you log in through the SSO Portal. This should all happen seamlessly in the background. A primary benefit is that you only need to remember one user name and password.

An active SSO session can last for up to 12 hours. An idle session will expire after 9 hours. If you log into an SSO application your session will expire in 9 hours. If during that 9 hours you access that or another SSO application, your expiration time will be extended for another 9 hours, up to a total of 12 hours after the initial login. Please note that some services may have additional security needs requiring you to re-authenticate during the 12 hour SSO window.

You will be forwarded to the SSO Portal Login page, and you'll have to restart the clock by logging in, which sets up your first 9-hour sliding window.

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 contact https://itsupport.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.

Please contact https://itsupport.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.


Community SSO Questions 

(Institute employees please go here)

The MAST and STGMS applications are currently supported by the MyST SSO login Portal.

Community members can go to the MyST Account manager to request a password reset. If you do not have an account, see How do I create an account (below).

Your email address is the identification you use to log in to the system. If you have forgotten your password, click on the "Forgot your Password?" link and you will be able to reset your password. If you need further help, please contact https://itsupport.stsci.edu and 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.

Go to https://proper.stsci.edu/proper/profile/lookup and enter your current or past email address. Additional help will be provided. If you do not have an account, see How do I create an account (below).

Go to https://myaccount.stsci.edu and click on the New or Guest User button. Enter your information on the prompted screens and click Create Account when done. An email confirmation will be sent to your email address with a link to create your password.

Go to https://myaccount.stsci.edu and click on the Registered User button to login and access your account. If you do not remember your password, go https://proper.stsci.edu/proper/password/forgot to request a password reset. An email confirmation will be sent to your email address with a link to reset your password.

To register for an account your password must be at least 12 characters long and contain at least one upper case letter, at least one lower case letter, and at least one numerical digit. Your password must not be the same as your email address, and your new password is compared against your previous 24 passwords. If you have any questions or concerns, please contact https://itsupport.stsci.edu.

Go to https://myaccount.stsci.edu and click on the Registered User button to login and access your account to change your email address. Notice will be sent to the current email address in your MyST account, with a link to approve the email change. If your current email address in your MyST account is no longer active, please contact https://itsupport.stsci.edu with your first and last name, the inactive email address, along with a brief explanation.
