Multi-factor authentication (MFA)

MFA requires additional verification to be provided in addition to your SSO username and password, such as confirmation of a temporary code sent to your phone.

To set up and configure Multi-Factor Authentication go to the MFA setup and management page. You should add multiple authentication methods so you do not rely on the same device, phone or internet connection.

The University of Oxford has a particularly high profile in teaching and research and we are under continuous cyber attack.  MFA was introduced to double lock our accounts and systems.

Microsoft Authenticator

Microsoft Authenticator is an app for mobile devices that can receive MFA authorisation notifications or provide one-time passwords.

Internet access is required to receive authorisation notifications.

Alternative Authenticator

If you already use an authenticator app then you may not need another.  A number of alternative authorisation apps are available, such as Google Authenticator and Duo Security, which can create one-time passwords for authorisation.

Authenticator apps should not require internet access or phone connectivity.

Authy

Authy is an alternative authenticator app available for most computers and mobile devices.

Having Authy installed on the computers you use should ensure that you can access your account even if your other devices are not available.

A phone connection is required for the initial set up, but it is not needed again after this.

Phone call

Mobile phones or landlines can receive an automated phone call to prompt for the press of a specified key for authorisation.

Text message

Devices able to receive text messages can receive an automated text containing a one-time password.

Security key

A security key, or hardware token, is a physical device that you plug into your computer.  Once set up, no other devices or connections are needed for authentication.

Please first contact your local IT support team for advice about purchasing and whether a security key is compatible with your devices as not all web browsers support security keys.  The security key must support FIDO2.

Security keys are supported by your local IT support team.

Older operating systems and applications may not prompt for a second factor, so may not be compatible with MFA.

Unsupported

The following are not supported before the version shown, or not at all.

  • Android 8
  • iOS 11

Security keys

Security keys function slightly differently as the browser must be able to prompt for it.  Most popular browsers can be used with Windows computers, for other devices the Chrome browser is likely to work but others may not.

MFA exemptions can be requested due to exceptional circumstances, such as accessibility issues.

Please first discuss all available MFA options with your local IT support team.  The circumstances for exemptions are limited and regularly reviewed as they reduce the security of an account, which could lead to severe consequences for the University through data loss, system impairment and reputational damage.

Exemptions are requested using the Exemption from Multi-Factor Authentication (MFA) service request and must be authorised by someone such as your manager, supervisor, tutor or administrator.
