# Recover a wallet

> This guide will walk you through how to use your users' backups to recover their wallet.

## Portal-Managed Recovery (default)

When using Portal-Managed Backups, you can simply call the `portal.recoverWallet()` function passing an empty string for the `cipherText` parameter. Portal will then fetch the `cipherText` from our backend and complete the recovery process.

```typescript theme={null}
// With Password backup
await portal.recoverWallet('', BackupMethods.password, {
  passwordStorage: {
    password: "${USER_PROVIDED_PASSWORD}"
  }
})

// With GDrive backup
await portal.recoverWallet('', BackupMethods.gdrive)

// With PasskeyBackups
await portal.recoverWallet('', BackupMethods.passkey)
```

<Warning>
  **WARNING**: To recover a wallet with the Portal SDK, your device must be configured to use passcode authentication. Please note that if you disable your passcode authentication after executing the `recover` function, you will need to run the `recover` function again.
</Warning>

## Self-Managed Recovery

By default, Portal manages storing both the encrypted client backup share and the custodian backup share for you. If you prefer to store and manage the backup shares in your own infrastructure instead of using Portal-Managed Backups, see our [Self-Managed Backups](../../../resources/self-managed-backups) guide.

Before recovering, you will need to retrieve the encrypted client backup share from your API. You will then provide the encrypted client backup share to `portal.recoverWallet`. Here's an example of how that might look in your code:

```typescript theme={null}
// Fetch the encrypted client backup share from your API.
const cipherText = await axios.get('/users/[userId]/user-backup-share?backupMethod=GDRIVE')

// Recover replaces your current signing shares (if there are any) with new ones.
await portal.recoverWallet(cipherText, BackupMethods.gdrive)
```

## Passkey Recovery

To recover a wallet that was backed up with a passkey:

<Tabs>
  <Tab title="Portal-Managed Recovery">
    ```typescript theme={null}
    import React from 'react'

    const RecoveryButton: React.FC = () => {
      const handleRecovery = async () => {
        // Portal fetches the cipherText automatically
        const address = await portal.recoverWallet(
          '',
          BackupMethods.passkey,
          {},
          (status) => console.log('Recovery progress:', status)
        )

        console.log('Recovered wallet address:', address)
      }

      return (
        <button onClick={handleRecovery}>Recover wallet</button>
      )
    }

    export default RecoveryButton
    ```
  </Tab>

  <Tab title="Self-Managed Recovery">
    ```typescript theme={null}
    import axios from 'axios'
    import React from 'react'

    const RecoveryButton: React.FC = () => {
      const handleRecovery = async () => {
        // Fetch the cipherText from your backend
        const response = await axios.get('{your_server}/users/[userId]/user-backup-share')
        const cipherText = response.data.cipherText

        const address = await portal.recoverWallet(
          cipherText,
          BackupMethods.passkey,
          {},
          (status) => console.log('Recovery progress:', status)
        )

        console.log('Recovered wallet address:', address)
      }

      return (
        <button onClick={handleRecovery}>Recover wallet</button>
      )
    }

    export default RecoveryButton
    ```
  </Tab>
</Tabs>

### Custom Domain Passkeys Recovery

If you configured a custom domain for passkeys (see [Custom Domain Passkeys](./back-up-a-wallet#custom-domain-passkeys)), use the following recovery flow:

<Tabs>
  <Tab title="Portal-Managed Recovery">
    ```typescript theme={null}
    import React from 'react'
    import { PasskeyOptions } from '@portal-hq/web/types'

    const passkeyOptions: PasskeyOptions = {
      customDomain: 'https://passkeys.yourapp.com',  // Your configured subdomain. This will be the same across all environments, even local.
      relyingPartyId: 'yourapp.com',                 // Your root domain. For local dev set this to `localhost`
      relyingPartyName: 'Your App Name',             // Displayed in passkey prompts
      usePopup: false,                               // Direct WebAuthn calls
    }

    const RecoveryButton: React.FC = () => {
      const handleRecovery = async () => {
        try {
          // Step 1: Authenticate with passkey to get encryption key
          const encryptionKey = await portal.authenticatePasskeyAndRetrieveKey(passkeyOptions)

          // Step 2: Recover wallet - Portal fetches cipherText automatically
          const address = await portal.recoverWallet(
            '',
            BackupMethods.custom,
            { customStorage: { encryptionKey } },
            (status) => console.log('Recovery progress:', status)
          )

          console.log('Recovered wallet address:', address)
        } catch (error) {
          console.error('Recovery failed:', error)
        }
      }

      return (
        <button onClick={handleRecovery}>Recover with Passkey</button>
      )
    }
    ```
  </Tab>

  <Tab title="Self-Managed Recovery">
    ```typescript theme={null}
    import axios from 'axios'
    import React from 'react'
    import { PasskeyOptions } from '@portal-hq/web/types'

    const passkeyOptions: PasskeyOptions = {
      customDomain: 'https://passkeys.yourapp.com',  // Your configured subdomain. This will be the same across all environments, even local.
      relyingPartyId: 'yourapp.com',                 // Your root domain. For local dev set this to `localhost`
      relyingPartyName: 'Your App Name',             // Displayed in passkey prompts
      usePopup: false,                               // Direct WebAuthn calls
    }

    const RecoveryButton: React.FC = () => {
      const handleRecovery = async () => {
        try {
          // Step 1: Retrieve cipherText from your backend
          const response = await axios.get('{your_server}/users/[userId]/user-backup-share')
          const cipherText = response.data.cipherText

          if (!cipherText) {
            throw new Error('No backup found')
          }

          // Step 2: Authenticate with passkey to get encryption key
          const encryptionKey = await portal.authenticatePasskeyAndRetrieveKey(passkeyOptions)

          // Step 3: Recover wallet with the encryption key
          const address = await portal.recoverWallet(
            cipherText,
            BackupMethods.custom,
            { customStorage: { encryptionKey } },
            (status) => console.log('Recovery progress:', status)
          )

          console.log('Recovered wallet address:', address)
        } catch (error) {
          console.error('Recovery failed:', error)
        }
      }

      return (
        <button onClick={handleRecovery}>Recover with Passkey</button>
      )
    }
    ```

    <Note>
      **Important:** You must have called `portal.storedClientBackupShare(true, BackupMethods.custom)` after successfully storing the cipherText during backup. If this was not called, recovery will fail with the error "Cannot run recovery, backup was not completed successfully".
    </Note>

## Progress Callbacks

You can learn how to handle the progress callbacks for `portal.recoverWallet` [here](./mpc-progress-callbacks).

## Next steps

Amazing! Your users can now have multiple backups and can easily recover their wallet. Next let's dive into handling sessions across multiple devices for your users.
