I hope that you didn’t click on any links in an email. If you did, it is likely you were directed to a phishing website which will look quite convincing as a Paypal login page.
I suggest ASAP to log into Paypal using the Paypal URL https://www.paypal.com/au/home/ and changing your password. If you clicked on an email link. it is possible that you have provided your password allowing these criminals to access your password protected Paypal account.
Edit: ~ The Paypal website in relation to determining whether such emails are legimate, indicate:
If you receive an email asking for documents, log in to your PayPal account. If it’s from us, you’ll see a notification that you can follow to upload the documents.
Thanks for the feedback
As @Fred123 mentioned, it’s a legit message from Paypal.
And as @phb pointed out, there’s a lot of scams. Interestingly, what prompted me to look at my account was a Paypal scam, although having worked in IT for 20+ years, I certainly didn’t click the link.
Anecdotally, I’m seeing a hell of a big rise in spam coming through over the past couple of weeks.
Signing off, and have a great weekend
