Why am I being asked to log in?
The service you requested requires that you identify yourself using your Stanford University Network (SUNet) ID. You must provide your SUNet ID and password to continue to the requested service or web page. (If you don't have a SUNet ID, see What if I don't have a SUNet ID, below.)
Under this system, called Web Authentication, or WebAuth, your single WebLogin gives you access to many other Stanford web sites besides the one you requested. In essence, you receive two keys when you log in: a key to the specific web site or service you requested, and a "master" key that opens other protected web sites as well. Those sites will admit you without requiring that you log in again. Note, however, that some Stanford services may require that you enter your login information each time, even if you are already logged in through WebAuth.
The keys last until you quit your browser program, or until they expire (they can last up to ten hours from the time of login). Always quit your browser before you leave your computer. Otherwise, someone else using the computer after you can get access to the Web—both to the sites for which you got specific keys as well as to any of the other Stanford web sites that accept the master key.
What am I supposed to do?
On the WebLogin page you came from, enter your SUNet ID and password and click on the Login button.
SUNet ID: Enter the login form of your SUNet ID, which is three to eight characters long.
Password: Enter the password associated with your SUNet ID. If you have forgotten your password, you can reset it yourself.
What if I don't have a SUNet ID?
Why is WebLogin asking if I use this machine regularly?
For machines you use regularly, WebLogin will remember single sign-on credentials for 25 hours and remembers two-step authentications for up to 28 days in some circumstances. By unchecking this box, WebLogin remembers neither and you have to log in again at the next WebAuth-protected site you visit.
Help! What did I do wrong?
Error messages and descriptions:
Missing or Incorrect SUNet ID and/or Password: To log in to Stanford WebAuth, you must provide both your SUNet ID and its password. It must be the login form of your SUNet ID, which is three to eight characters long (for more information on SUNetIDs, see What am I supposed to do?). If you have forgotten your password, go to Accounts to reset it.
You took too long to login: You must enter your SUNet ID and password within two hours of the WebLogin screen appearing. Backing up to the WebLogin page and trying again does not work; you must re-initiate the request for the web page or service you want.
Why am I being asked to authenticate?
When additional security is required, you are asked to use two-step authentication. You can authenticate using various methods, including push notification, SMS text message, authenticator app, callback, or printed list.
You can be prompted tor authenticate in a variety of situations including:
- the site you are authenticating to requires it,
- your browser or device hasn't been used before or hasn't been used in 28 days,
- or you choose to require authentication each time you log in.
Once prompted, you must use your two-step method to log in.
If you are unable to authenticate, you can go to Accounts and get a one-time two-step authentication code after your verify your identity. You can also change your two-step authentication devices, methods and settings at Accounts. If you need assistance, please call the IT Service Desk at 650-725-4357 (5-HELP).
