Backup
💾 Retrieve backup
Suppose the user is already enrolled and you have your backup system in place. To retrieve the Keyless backup data and backup key invoke the
Keyless.getBackupData() method. You can store the backup data and backup key to let users restore their account with Keyless.The backup data (type:
ByteArray) and backupKey (type: ByteArray) are required to restore an account with Keyless. Save the Keyless backup in a secure data store.1
fun retrieveKeylessBackup() {
2
try {
3
val backup = Keyless.getBackupData()
4
val backupData = backup.backupData
5
val backupKey = backup.backupKey
6
// Handle your backup system logic
7
} catch (e: KeylessException) {
8
// Handle exception
9
}
10

♻️ Restore from backup
Suppose your backup system provided the Keyless
backupData and backupKey that was saved when the current user was enrolled. You can invoke the Keyless.enrollFromBackup(backupData: ByteArray, backupKey: ByteArray) method to let the user restore their Keyless data and enroll from backup.1
fun enrollFromBackup(backupData: ByteArray, backupKey: ByteArray) {
2
try {
3
val backup = Keyless.enrollFromBackup(backupData, backupKey)
4
} catch (e: KeylessException) {
5
// Handle exception
6
}
7
}

As with
Keyless.enrollCustomToken() when Keyless.enrollFromBackup() finishes, the enrollmentFinish delegate method gets called. In case of errors, prompt the user to try again.If the process was successful, stop the loading indicator and navigate to the next screen of your application (e.g. success or main view).
1
override fun enrollmentFinish(
2
keylessID: String?,
3
enrollmentResponse: String?,
4
error: KeylessException?
5
) {
6
// Please make sure to use runOnUiThread() if you need to handle UI changes
7
if (error != null) {
8
Log.e(TAG, "Enrollment failed: " + error.title +
9
" Message: " + error.message + " Code: " + error.code +
10
" Cancelled by user: " + error.userCancelled);
11
12
// Show error alert
13
// Revert any changes up to this point
14
15
return
16
}
17
18
// Handle successful enrollment
19
// At this point the sign up process finished successfully
20
// Let the user know that signing up was successful and navigate to your next screen like the main screen
