Step 2 of 7: Confirm the account
Type the email address shown under your name on the Security info page.
This makes sure you are setting up your UCSH work account and not a different Microsoft account. It is a safety check: if you cannot find the email, you can still continue.
- On the Security info page, click your initials in the top-right corner, then Sign out.
- Close that browser tab.
- Go Back to the first action of Step 2 in this guide, click Open Security info page again, and sign in with your @ucsh.com email.
You're finished
Your UCSH account is now protected by the Microsoft Authenticator app, and text-message codes are turned off.
Next, see what signing in looks like from now on. It takes about a minute.
Three rules to stay safe
- Only tap Yes when you are signing in yourself, right now.
A pop-up you did not expect means someone may have your password. Tap No, it's not me and contact the IT helpdesk straight away. - Never give anyone the number or a code.
Not by phone, email or chat. IT will never ask you for it. - Getting a new phone? Tell IT before you reset or trade in the old one.
If your phone is lost or stolen, contact IT immediately.
