Having an issue with restoring my backup to my new iphone. Its asking me for backup password and dont ever remember one. Help ?

Sorry,but if you used the option to encrypt your backup and can't remember the password you set up, you can't restore from that backup anymore.

You'll have to start all over again without the backup data, the backup password can't be reset.

There is no way to recover your information or turn off Encrypt Backup if you lose or forget the password.
