How does BT know when "caps lock" is used? I thought the keyboard was secure.

Well, the keyboard is…

However, what you type into it doesn’t stay in the keyboard. It ends up on the website you are typing into, of course.

I think to get a sensible answer you’ll need to explain the context of your question a bit more.

Clearly any website "knows" about whatever you type into that site, including whether lower case or upper case characters have been typed.
It can't though "know" whether you've used the capslock or have merely pressed the uppercase key each time you typed uppercase characters.
And a website "knowing" what characters you've typed is not a security concern unless you deliberately type something sensitive like your passwords, or bank account details on a non-secure site
Perhaps you could explain what your concern actually is?

Any company needs to know when you input something into their site whether upper or lower case is used, or passwords would be a whole less secure, let alone any other input you put in like searches or composing an email - BT is not alone in this, every website operates in much the same way.

Thanks for the replies. This only happens with BT. If I change caps lock, before I send anything, BT knows of that change.

I wondered how they could know the setting was wrong beforehand.

Thanks.

It’s not just BT that warns users when they have their caps lock on during password entry. Any modern browser allows the website to fetch the state of the keyboard modifier keys. For example in JS it’s via getModifierState('CapsLock')

Hi, Thanks for the explanation. As this has only happened with the BT site I assumed there might be a problem.

Cheers.
