Accounts Overview

This article aims to demystify how logins work in Princeton ISD. If you have any questions that are not addressed here, please call 2099 for assistance.


Source of Authority (SOA) A Source of Authority (SOA) as it applies in Technology is a system that provides the official record of something. Other systems will get their information from their SOA.
For example: Infinite Campus is the SOA for basic student information and rostering.
Identity Provider (IdP) An Identity Provider (IdP) is an SOA for user logins. An IdP is used to tell a system that you are logging in to whether your login credentials are valid.
Active Directory (AD) Active Directory (AD) is a database of user login information. It is used to authenticate several district systems including any computer that is not a Chrome device. It is also a SOA for certain services. This is sometimes referred to as your "network login."
Single Sign-On (SSO) Single Sign-On (SSO) is a technology that allows a service like Google or ClassLink to act as an IdP for another service. There are several types of SSO but they are all essentially one service sending information to another service to allow you to log in without typing a password.
For example: When you log in to ClassLink and click on the Pearson icon, ClassLink tells Pearson to log you in. You do not have to enter a password in Pearson because ClassLink tells Pearson who you are.


Every person in Princeton ISD has at least two logins. One is stored in Active Directory (AD) and one is stored in Google. These logins are not connected in any way and it is possible for usernames and passwords to differ between these systems.

Your AD login is used when logging in to any computer that is not a Chrome device. It is also used for logging in to services like the Knowledge Base and ClassLink.

Your Google login is used when logging in to a Chrome device like a Chromebook. It can also be used to log in to 3rd-party websites and to ClassLink (assuming you have linked your Google account to ClassLink).

What is Classlink?
Why do I need ClassLink?

Most 3rd-party resources that are provided by the district use ClassLink to log in. This is accomplished using Single Sign-On technology or by automatically filling passwords on supported sites. A full list of supported sites is available here. It can also be used to store and fill credentials in other websites that are not directly rostered by the technology department.

Please Note: Websites that use auto-fill to log in will have a brief delay between the website appearing and the form being filled. Please do not enter any credentials while this is happening as it may interrupt the process.

How do I log in to ClassLink?


How are student accounts created?

Student accounts are created automatically using data pulled from Infinite Campus. A detailed article has been written on the subject which is located here.

Please note: You must be logged in to the knowledge base to see the article. The Knowledge Base uses your AD login.

How do I log in to...?
  • If the service is part of this list (link) use ClassLink to log in.
  • If you are trying to log in to the Princeton ISD website put in a ticket so that our webmaster can assist you with getting logged in.
  • If you are trying to log in to Eduphoria, your username is your district email and your password can be reset using the "Forgot Password?" link on the Eduphoria login page (link). This login is separate from both AD and Google logins.
  • If you are trying to log in to the TEKS Resource System your username will be your Princeton ISD email. If you are unable to reset your password, put in a ticket so that we can assist you further.
  • If you are trying to log in to Infinite Campus contact your campus PEIMS coordinator.
My students are trying to log in to a district provided site but their logins are not working.

There are several issues that can arise when attempting to log in to a service via ClassLink. Most are listed below along with some troubleshooting steps.

Students report invalid password/access denied

This is usually one of two issues.

  • The student didn't wait for ClassLink to fill their credentials and tried to type them. This is usually solved by observing the student as they try to log in.
  • The student was previously prompted for a password and entered an incorrect password. This is resolved by following the instructions here under the heading "The student receives an Incorrect Password error from the app"
Students are prompted by ClassLink to enter a password
  • If the resource they are trying to access is on this list (link) it could be that they do not have an account in that resource yet. This can happen if they are a new student or they do not have a valid State ID in Infinite Campus.
  • If the resource is not on that list, it is not managed by the technology department. If they know their credentials for the service they can enter them when prompted after which they will be automatically filled for all future logins.

To get a student's AD or Google password reset please put in a ticket under the Password Reset category or call 2099.

What grade levels are required to change their passwords?

Starting in 6th grade, students are required to change their password when they log in for the first time and after every password reset. This aids in protecting their district accounts and data from being compromised.
