When you try to access the VPN server, you’re prompted to authenticate with your VPN credentials.
The VPN authentication prompt contains the following input fields:
In the username field, enter your VPN username.
In the password field, enter your VPN password, followed by the character separator previously defined in the PacketFence Multi-Factor Authentication section, and the second factor. Depending on your preferred authentication method follow these steps:
a. To authenticate with a push notification, enter the word push. This sends a push notification to your trusted device. You can then tap Allow to acknowledge that the login is legitimate.
b. To authenticate with an SMS, enter the word sms. Optionally, you can also enter an index, like sms2 to use your second trusted smartphone. This sends a verification passcode to your trusted mobile device. The first authentication challenge is then rejected. In the second authentication attempt, the VPN client prompts you to enter your username in the username field. Next, in the password field, enter your password followed by a character separator, and the passcode that you received via SMS. Your input in the password field would look like this: your passwordyour SMS code.
c. To authenticate with a phone call, enter the word phone. You receive a phone call on your trusted authentication device. During the call, you can hear the voice message with your verification passcode. The first authentication challenge is rejected. In the second authentication attempt, the VPN client prompts you to enter your username in the username field. Next, enter your password followed by a character separator, and the verification passcode that you received during the call. Your input in the password field would look like this: your passwordyour passcode.
d. To authenticate with a push TOTP, third-party OTP device, bypass code, or hardware token, enter the passcode that was generated by your authentication device or the bypass code that you received from your help desk. Your input in the password field would look like this: your passwordyour passcode.
e. To authenticate with one of the authentication devices that you have enrolled, enter the authentication method and the index of this device. For example, enter the word push2, which sends the authentication request to your second device. You can then tap Allow to acknowledge that the login is legitimate.
