Logging in with Google Authenticator
Requirements
- a device (such as a laptop) on which you want to use a service with multi-factor authentication (such as VPN)
- a mobile device running iOS or Android with a precisely set time and the Google Authenticator app enabled
- you have activated multi-factor authentication for the service in advance using the authentication app Google Authenticator
In the authentication app, a one-time password is displayed for the corresponding account, which is renewed every 30 seconds. For VPN, for example, this is the account ZID (ZID Universität Wien: UserID). How much time you have until the next one-time password is generated is shown by the level of the circle on the right.
