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. 
// 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: 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.

​
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 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: 
// 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.GoogleDrive)
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.
