I'm annoyed by lots of things that are justified as 'security', particularly when they are pointless and repetitive.
I made four transactions on PayPal this morning, all from the same MacBook Pro that I've had for years, and each time PayPal sent me an email warning that someone had logged in as me 'from a new device'. It has even informed me that I am using a 'trusted device', and then almost immediately sent me an email saying it is a new one. I don't have a VPN and I haven't trashed my cache or anything, but something seems to keep triggering PayPal's 'security' system for no useful purpose whatever.
I suspected that it might be something in Safari that is re-setting. For 'security', obviously...
