Is it possible to Remove Owner History from the GWMT?

[BeytzNet]

Hello,

As a site owner, I've worked with several SEO firms in the past.

Even though a long time has passed, they still appear in the GWMT list of admins (though inactive).

I wouldn't like other companies and consultants see that in the future.

Is there a way to remove them?

Thanks

Yes delete anyone who has access ASAP. WMT is a very powerful tool, someone can go in and completely deindex your site with a few clicks.

Also WMT was having a hacking issue a couple months ago where old accounts were getting reactivated. Definitely keep an eye on who has access to WMT.

Thank you Irving and Matt,

The previous companies were removed but their names and emails still exist in the history (they were given an Owner authority).

Is there a way to remove them from there?
Also, what authority should a company be given?

Thanks
