title: Can the ID in the ASpNetUsers table change for any reason
body: <p>I'm testing the new asp.net identity. I added a new table to the SQL database to gather more information about each subscriber (name, family name, city etc). I don't want to use the existing ASpNetUsers for that matter. I want to use 2 different tables. To identify the same subscriber in the 2 tables I'm using the Unique Identifier that is added automatically to the ASpNetUsers table. Couple of days ago I noticed that one of the ID in the ASpNetUsers has changed. Dunno how. Is that possible? Can the ID of a registered subscriber change in the ASpNetUsers table for any reason (changing password, confirming a new password etc? </p>
  
  <p>Thanks </p>
