Can I change the timer on the Dead Man’s switch?

Yes, it can be adjusted at any time to suit your needs, provided you have a platinum account.

12 months is the default DMS setting. If you do not login to DieFi for 12 months, the beneficiary or beneficiaries will be contacted. You will get alerts/reminders before the DMS gets activated to ensure you did not forget to login to your DieFi platform.
