When a UW Web site needs to know your identity, it automatically
redirects you to the "weblogin" service. The purpose of this trip
is to authenticate who you are by requesting your UW NetID and password,
which only you should know. Many UW Web sites use the "weblogin" service
in this way, including MyUW,
Web Alpine, Student Personal
Services, Employee Self-Service, and the Catalyst Tools.
When you arrive at the "weblogin" service for the first time during
a browsing session it displays a login page which asks you to log
in with your UW NetID and password. It may ask for SecurID too, if
a higher level of assurance of your identity is required.
Before entering your UW NetID and password, always verify that the
login page comes from the "weblogin" service. The address should be
https://weblogin.washington.edu. This is the only Web site
address you should trust with your password.
Enter your UW
NetID and password as needed and click the "Log in"
button. Make sure you enter your UW NetID using all lowercase
characters, and do not enter your full UW email address. Your UW
NetID is the part of your UW email address to the left of the @ symbol
(e.g. "myuwnetid" is the UW NetID in the email address email@example.com).
If login succeeds, the "weblogin" service automatically redirects
you back to the initial UW Web site that needed to know your identity.
It receives your UW NetID (but not your password) as proof of who
you are and now can decide what to do with you.
If login fails, make sure your Caps Lock key is off and your Num
Lock key is on. Then try again.
The next time a UW Web site needs to know your identity, the same
process unfolds, beginning with another trip to the "weblogin" service.
However, this time you may not be asked to log in.
Namely, when you are redirected to the "weblogin" service a second
or third time or more, it detects that you have already logged in,
so you can be reauthenticated without having to enter your UW NetID
and password again. This feature is known as "single sign-in" and
the "weblogin" service abides by it most of the time. It reduces the
number of times you have to log in during a single browsing session
and simplifies how to log in to several Web sites over a short period
The standard lifetime for this "single sign-in" period is 8 hours
or until you log out, whichever comes first. During this period you
may not notice return trips to the "weblogin" service, although, if
you watch closely, brief indications may show up in your browser's
To protect your privacy, remember to completely exit your browser
when you are finished browsing. Exiting your browser deletes the "cookies"
the "weblogin" service and other UW Web sites use to remember that
you are logged in. To learn more, review how
