Error 400, 401 and my email

[Jimothyyy]

This is my first github account and question but I would like to ask why shortly after updating to the new version my auth token suddenly stopped working citing error 401. I then attempted to fill my Auth token to allow it to work but it then cited error 400 which also included my email address connected to the account in the error. Is it normal for undiscord to know what the email on the account is and for it to deny the Auth tokens despite it being filled out? I later changed my email and password on the account out of concern.
