# Import recovery key share

> This operation imports and decrypts the JSON data of recovery key shares, created by the [Export recovery key shares](https://www.cobo.com/developers/v2/developer-tools/ucw-sdk/ucw-class/export-recovery-key-shares) or [Export Secrets](https://www.cobo.com/developers/v2/developer-tools/ucw-sdk/ucw-class/export-secrets) operations. To meet the threshold requirement of [the Threshold Signature Scheme (TSS) specified in your User-Controlled Wallets](https://manuals.cobo.com/en/portal/mpc-wallets/ucw/project-management#overview), you must call this operation the required number of times to import enough recovery key shares.
