Recovery Group

Recovery Groups serve two main purposes: Recover the whole private key and create a new Main Group if your Main Group and backup copy are lost or compromised. To learn more about backup and recovery, see Back up holder groups and Recover key shares.

Similar to creating the Main Group and Signing Group, you have the option to choose either mobile co-signer or API co-signer when creating the Recovery Group. Make sure you understand the primary purposes and prerequisites of each co-signer type before proceeding further.

After you’ve chosen a co-signer type and set up the prerequisites, follow the instructions below to create a Recovery Group. Note: Only the users who have been assigned the Operator user role in the organization can create a Recovery Group.
