Hi @RubikTSV,
There is no cross-platform progression in Apex Legends, so I'm afraid your progress from PC will not carry over to Xbox.
If you're having trouble with logging into your EA Account or with resetting the password it would be best to get in touch with the EA Help team so they can take a look. I'm afraid we aren't able to help with account issues here on Answers HQ.
For more details on how to set up a case with the team check out the EA Help website. You can also speak with them over Twitter or Facebook instead, if you prefer.
