How websites tell an automated browser from a person: the TLS handshake, the fingerprint, mouse movement and the test sites that read them.
A site can judge a browser before its first script runs and keeps judging it until the last click. The articles here go layer by layer, from the TLS handshake through the fingerprint to the way the mouse moves, and each one compares our engine with a real Chrome on the same machine.
To see what your own browser gives away, the check page reads it without an account.
