Once users successfully back up their wallets, they can generate a new set of signing shares irrespective of the SDK in use. Furthermore, both the new and old sets of signing shares can be used simultaneously, thanks to portal.provisionWallet. This provisioning relies on the user already having a successful set of backup shares. While provisioning, the wallet fetches the encryption key from the user’s cloud storage provider to decrypt the encrypted client backup share. Note that our SDK handles the decryption; you only need to supply the encrypted client backup share. For wallet provisioning support, consult the recovery documentation to establish the necessary /backup/fetch webhook. Also, ensure the user has successfully completed the backup process. Here’s how to implement portal.provisionWallet: 
import axios from 'axios'
import React, { FC } from 'react'
import { Button, View } from 'react-native'
import { BackupMethods, usePortal } from '@portal-hq/core'

const ProvisionWalletButton: FC = () => {
  const portal = usePortal()

  const handleProvisionWallet = async () => {
    // Get the existing encrypted client backup share from your API.
    const backupShare = await axios.get('/clients/[clientId]/backup')

    // Set the new signing share by running provisionWallet.
    await portal.provisionWallet(
      backupShare,
      BackupMethods.GoogleDrive, /* or BackupMethods.iCloud */
    )
  }

  return (
    <View>
      <Button onPress={handleProvisionWallet} title="Provision your wallet" />
    </View>
  )
}

export default ProvisionWalletButton
And that’s it! You’re now equipped to support multiple sessions across different devices for your users.
