Authy is a free application which provides a secure way to protect your online accounts and can be used as a verification method for mutli-factor authentication (MFA) on your Oxford Single Sign-On (SSO).
There is no requirement for an administrative password to authorise the installation and it will not be found in the Oxford Applications installer. Authy can be installed on either a mobile device or a dekstop computer.
Once Authy is setup, it does not require a phone number for verification. However, a phone is required for initial setup of both the mobile and desktop Authy apps.
