After changing my user name, how do I see my previous user names?

After GDPR, social networks have a data access tool where the user can see the previous user names and even biography texts and display name texts.

Is the same possible on Stack Exchange Network?

    I don't think they are kept, your name is not how the system tracks you AFAIK. You are tracked by your ID 379894 and the name is just a bit of flair.

    As for GDPR, there is option somewhere to download all your data, doesn't it contain your past names? I didn't try downloading it yet so can't really know. Commented Jul 11, 2018 at 22:48
  • @ShadowWizard Not sure. On some social networks out there, the user data archive contains the username history, on others it does not.

You can see your past names only up to 90 days, not before. In case you changed name in the past 90 days, go to your Edit Profile & Settings page, there you'll see "recent names" link below the Display Name field:

Click the number, and you'll see your recent names and when they were last used:
