Backup Flows

​

BF-7. Factor Deletion

• This flow is triggered when the user deletes a Main Factor from the UI.
• Sync Factors are not manually removed by the user. This is usually done through other flows (e.g. when logging out).
• Currently, Passkeys are enrolled into Turnkey to provide a fallback mechanism in case a Sync Factor is no longer available. When the requested operation cannot be completed with the Sync Factor (see PUBLIC_KEY_NOT_FOUND error), the client will use the Passkey to execute the operation instead.
• Transitory: Currently, removing a Passkey factor while there is still an OIDC factor is not supported. This is because a Passkey factor is required to manage other factors (restriction on backup-service when adding other factors) and the Passkey is used to recover access to Turnkey should the Sync Factor fail.
• Future Note: The current flow assumes that Turnkey is only used for OIDC Factors. This may change in the future (e.g. to support non-PRF Passkeys).

​

BF-8. Backup Deletion

• Backup Deletion is triggered from either:
  • The user removing the last Main Factor (see BF-7).
  • The user requesting full account deletion of World App.
• Backup Deletion will clear all data related to the backup.
