Backup Options

Password/Pin Backup

Allow customers to create a password/pin. Customers 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.

                    // Do something with the status, such as update a progress bar
                    // or log the progress
                    Log.println(Log.INFO, "[Portal]", "Backup status: ${status.status} is done: ${status.done}")
                }
                
                // Send the backup share to your API and store it.
                exchangeApi.storeCipherText(user.id, backupShare)
                
                // ✅ Notify Portal that the backup share was stored! 🙌
                portal.api.storedClientBackupShare(true)
            } catch (err: Throwable) {
                // ❌ Notify Portal that the backup share was not stored.
                portal.api.storedClientBackupShare(false)
            }
        }
    }

Note - If you dont pass a backup option into portal.backupWallet() we will default to GDRIVE backup.
