Description​

BACKND SDK provides the guest login function utilizing the custom(ID/password) account function.

  • Guest login accounts can be changed into Google/Apple/Facebook federation account.
  • Guest login accounts can perform token login.
  • Guest accounts log in based on the locally stored account information.
  • When local data deletion, app re-installation, device change, or local data damage occurs, the user cannot attempt guest login using the given account.
  • Even if the locally saved account information is deleted, the user data stored in the server remains.
danger
  • BACKND does not provide separate login methods for guest accounts that have been restricted due to the deletion of locally saved account information.
  • The console does not provide the function to change ID/password of the guest login account.
  • Services such as data restoration and data transfer are not provided for guest accounts.
  • In case of local data deletion, app re-installation, device change, or local data damage, please make sure to notify the user that access to the guest account will not be available.
  • When email information is registered in the guest account, you can send a password initialization mail. With this email, password initialization will be available. However, if the password is initialized, the password of the guest account in SDK and the password of the actual account will differ.
    In this case, the user may log in only via a custom login.

Guest login​

When the guest login method is called, the existence of guest account information stored locally in the device is checked.
The way of handling the method varies depending on whether the system has guest account information or not.

  • The ID of a guest account is generated in the format of guest-0514db55-6bd3-46f3-a4dd-0cc5a57ddf53.
    • guest- is a value that indicates that the account is a guest.
    • The suffix string is a UUID value that is not duplicated.
  • A guest account is regarded as a custom sign-up account. In BACKND Console, the type of sign-up is also displayed as customSignUp.

When guest account information exists in the device​

A custom login is performed using the stored guest account.

When guest account information does not exist in the device​

A custom sign-up is performed by creating an ID that does not match with another user.
When the sign-up succeeds, guest account information is stored in the device locally using BACKND file system function.
