I was using Facebook on Opera when I needed to clear the cache history.
I then shut down the laptop and went to do something else.
When I came back, I launched Opera (which opened the latest page I was on before shutting down the laptop).
On the Facebook login page this email address appeared:
1580979448583207_xdzdsmbm@tfbworknw.net
It was just pre-written in the email field. There's no record of it in the field history. Also no password was set.
I'm the only one using this laptop. Ever.
If that was a random e-mail address, I would consider being hacked (for whatever reason), but this address?
It seems the domain name is from Facebook, but almost no trace of it on Google.

What is it? And more important, where does it come from?
Any reason to be worried?

This is due to do your usage of Facebook Workplace prior to login in to personal Facebook. The auto-populated e-mail 1580979448583207_xdzdsmbm@tfbworknw.net was the cache from Facebook Workplace.
