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.

Enter this one-time password in the appropriate place on the device with which you want to use the service (for example, in the One-time password field when logging on to the VPN).

 Note

The one-time password must be sent to the corresponding application before the 30-second validity period expires.
