PingMFA Campaign - Terms of Service | Ping Identity
You can expect to receive one-time password codes used for authentication purposes in association with this PingMFA Campaign once you opt-in to receive them.
You can cancel the SMS service at any time. Just text "STOP" to the short code. After you send the SMS message "STOP" to us, we will send you an SMS message to confirm that you have been unsubscribed. After this, you will no longer receive SMS messages from us. If you want to join again, just sign up as you did the first time and we will start sending SMS messages to you again.
If you are experiencing issues with the messaging program you can reply with the keyword HELP for more assistance, or you can get help directly at email@example.com or by calling us at +1 855-355-PING (7464).
Carriers are not liable for delayed or undelivered messages
As always, message and data rates may apply for any messages sent to you from us and to us from you. You will receive one message for each authentication attempt as required by your employer’s or service provider’s authentication policy. If you have any questions about your text plan or data plan, it is best to contact your wireless provider.
