When you sign in with your @u or @un Microsoft 365 account, the “Let’s keep your account secure” screen may appear. After you select “Next,” you may then see the “Sign in faster with your face, fingerprint, or PIN” screen.
These screens guide you through setting up a passkey for signing in to Microsoft 365.
Currently, setting up a passkey is optional.
If you would like to set up a passkey, please refer to the following instructions:
for Windows: How to sign in to Microsoft 365 using passkeys –with Windows Hello–
for Mac: How to sign in to Microsoft 365 using passkeys –with iCloud Keychain–
(Please log in with your Unified Authentication ID/PW when accessing this page.)
If you do not want to set up a passkey, on the “Let’s keep your account secure” screen, select “Not now” or simply close the screen.
If you did not receive a code when signing in to Microsoft 365, or if you did not receive a code due to a change of device, please click here.

Information signed in with other previous accounts such as @s.tsukuba.ac.jp account may be saved in the browser cache and cookies. Because of this, even if you intended to be signed in at @u.tsukuba.ac.jp, you may be signed in at @s.tsukuba.ac.jp.
Please delete your browser cache and cookies, or check if it’s available in other browsers such as “Microsoft Edge”, “Google Chrome”, “Firefox”, or use different device.
Logging into the Office 365 Portal requires a new password, which is defined by the user upon signing up for EES advantages instead of the unified verification password.
Apparently, you can receive some charge-free services from Microsoft by creating a Microsoft ID using your personal email address. That is not related to this service of ours. We do not recommend using your @s, @u or @un email address to create your Microsoft ID. That could cause a problem when you receive services from the University of Tsukuba.
Do it by
- Sign-in yourself in https://myaccount.microsoft.com/
- Click the “My sign-ins” in the left-edge menu
- Your recent active sign-in history is displayed
For detail, also refers to Microsoft’s newest document. (eg. search keywords “Microsoft365 recent activity” and read the Microsoft Support in that page.)
If you also want to change your password, please read this QA, ignoring the URL told in that document.
Part-time lecturers, professors, associate professors, special professors, visiting professors, and adjunct researchers who wish to receive the @u.tsukuba.ac.jp email address should submit an application form below and attach a copy of an ID card issued by the university.
