Background
To increase the security level of the department computer accounts we're currently phasing in a requirement to use MFA when logging into the department SSO.
We strongly recommended using Passkey instead of Authenticator App (OTP) when possible,
as it's a much faster and more integrated experience compared to entering codes from an mobile phone.
Though the Authenticator App is a very good thing to have available as backup if/when your regular device is not available, so setting up both types of MFA devices is a good idea.
Note:
The first MFA type you setup will be used as the default MFA in the login flow for your account, if you've setup OTP first but want to switch to using Passkey by default, contact support and we'll change it.
Adding a MFA device
Go to https://s.cs.umu.se/go/mfasetup and login with your CS-username and password. If you already have a MFA device configured you'll need to use that as well.
If you've lost all MFA devices, contact Support for help.

Go to Account Security -> Signing in
Types of MFA
There are two options of MFA devices that you can use
Authenticator Application
An OTP-code generating application, ex. Microsoft Authenticator app that you likely already use for your Umu-id MFA.
Though many other choices exists, such as:
- Yubikey (via
Yubico Authenticatorapp) - FreeOTP (another OTP app for Android users)
- andOTP (another OTP app for Android users)
- and many Password Managers such as 1password/lastPass/Bitwarden/.. can typically also act as an OTP app
Passkey
A hardware security key, ex. and Yubikey, or even just your regular computer or mobile phone itself.
Also many Password Managers such as 1password/lastPass/Bitwarden/.. can typically also store/use passkeys.
Note:
Using your computer as a security device, ex. if your computer has a built-in fingerprint sensor, or with a PIN-code, is currently not supported by any browser on Linux, so it will only be possible for people running Windows or MacOS.
Adding a MFA device - OTP Device (ex. an Authenticator app in your phone)
Click the Set up authenticator application link to start the process

Enter a descriptive name in the Device Name field. If you have multiple MFA authenticator-apps configured you'll need to select which one to use when authenticating,
so something short and informative is good here.
'MS Authenticator', 'Yubikey', 'freeOTP', ..
Scan the QR-code with your Authenticator app,
then type the 6-digit code shown in the app into the One-time code field in the browser.
