Backup methods

A guide that goes over all of the various backup methods your users can use.

Passkey + Enclave

Allow customers to create a native passkey on their device that is used to authenticate into a secure enclave that holds the encryption key for the user. Customer's passkeys are backed up to the native cloud storage for their device.

Implementation Requirements

  1. Install react-native-passkey

  2. Initialize passkey storage as a backup option in the Portal Config Object.

  3. Configuring the relying party

Relying party

A relying party is a trusted domain that is tied to the public key credentials of your users for their passkey . We offer the option to use as your relying party domain. It requires you to add as an Associated Domain in your iOS application and share your team id + application bundle id. If you already have your domain as a webcredential for your application then you can simply pass in your domain as the relying party and everything should work.

Use Portal as your relying party

  1. Add as a web credential domain in your app.

  2. Share your app bundle id and team id with the Portal Team.

Use your own relying party

Ensure you have set up your associate domain correctly in your app and that you are serving an aasa file from your relying party domain. You will need to be sure you have the webcredential field set properly for your app in your aasa file.

Allow users to create a password/pin. Users can either remember the password or store it in a password storage manager.

Implementation Requirements

  1. Create a UI for password input.

  2. Enforce password requirements. Customer can choose between password, PIN code, passcode, or any other text-based input.

  3. If user forgets password there are no additional recovery options.

import axios from 'axios'
import React, { FC } from 'react'
import { BackupMethods, usePortal } from '@portal-hq/core'
import { Button, View } from 'react-native'

const BackupButton: FC = () => {
  const [password, setPassword] = useState<string>('')
  const portal = usePortal()
  const handleBackup = async () => {
    // Get an encryped client backup share from running backup.
    const cipherText = await portal.backupWallet(BackupMethods.Password, { passwordStorageConfig: { pasword } })
    try {
      // Send the backup share to your API and store it.
      await'{your_server}/users/[userId]/user-backup-shares', {
        data: { backupMethod: "PASSWORD", cipherText }

      // ✅ Notify Portal that the user backup share was stored! 🙌
      await portal.api.storedClientBackupShare(true, "PASSWORD")
    } catch (error) {
      // ❌ Notify Portal that the user backup share was not stored.
      await portal.api.storedClientBackupShare(false, "PASSWORD")
  return (
      <Button onPress={handleBackup} title="Backup your wallet" />

export default BackupButton
