Several comments in this thread suggest solutions make no sense. Perhaps the commenters have never seen how delegated access works in Gmail?

Once you've been delegated access to a Gmail account, it appears in the list of accounts you can switch to, but only within the Gmail web UI.

When you explicitly switch to that account, you see the other person's mailbox. If you never click on the switcher, you wouldn't even remember you had access.

Given the above:

- filtering makes no sense, because the mail items never appear in the same mailbox anyway

- changing password makes no sense, as you can only access gmail and not the whole Google account
