It seems that PayPal doesn't allows the most secure way to authenticate anymore.

So it isn't possible to configure any new token you get somewhere for PayPal.

This change happened somewhere between September 2018 and January 2019. Maybe it's also region locked. I was able to configure a new token Sept 2018 using a USA located internet connection (no VPN, direct connection inside America), but I couldn't find the same thing using an EU based internet connection.

Same thing for ebay by the way. If you'd have one of the plastic symantec tokens (with exchangeable batteries) - not the card shaped ones and if you had registered it on PayPal or Ebay mid-2018, you're good to go for multiple years to come - but if you didn't do this I'm afraid to say that new Symantec tokens won't be possible.

Note: I don't work for Symantec or PaPal or Ebay. It's just what I discovered in research for what happened to these Symantec tokens (they're rarely sold nowadays - production seems to have stopped there)
