When signing into my email accounts today a message appeared 'auth.bt.com wants access other apps and services on this device Allow or Block. I blocked. There seems to be no where on My BT to be able to report this. I assume this is a scam? Has anyone else had this?

Is it the BTMail app that you are using?
If it is it may be wanting access as per what the the BTMail app " collects shares and handles"

I never got the box on my browsers DuckDuckGo, Firefox and Opera but when I tried Edge and Chrome it did come up on them, but only the first couple of times I tried.
It would appear to be something that BT have implemented which I suspect has something to do with the browsers being able to be used on phones and tablets in "Mobile" mode but I have no idea why it has carried onto the "Desktop" browser.
I will ask the moderators if they can throw any light on it.
