Account Approvers are the users that have the ability to approve or reject payments by providing their Digital Signature. When creating an Account, you have the ability to set the Approvers and the Required Approvers threshold.
Only Business Organization accounts can have multiple approvers / have their approvers updated. Your individual Organization account only has one approver by default.
Select Account Approves upon account creation
Select required approvers threshold after creating an account
You can update the approval threshold at any time from the Approvers view within an Account. The change will require you to meet the existing approval threshold from before the change.
Because Accounts and their associated transactions are recorded on a blockchain, approvers are linked to a user's Digital Signature. It is critical that you maintain access to your Digital Signature to protect your assets.
