Previous user existing data is not affected

This looks pretty good to me. I don't see any major problems and after testing locally it seems that sqlite at least is working well. I didn't do too much testing outside of local stuff, and I'll be honest I'm not super familiar with postgres. However, everything seems pretty standard and it looks good to me.

Great to hear. Thank you for your time and effort in reviewing! 😄
I have tested this PR on Local [SQLite, MySQL, PostgreSQL] and Render [SQLite], which shows that the user's previous data still exists and has not disappeared.
